speed3 CEL troubles dealer can't find problem

[integrrac]

So over a month ago my CEL lit up on my 2007, the dealership said I needed a new fuel pump. Fair enough, its all under warranty and my car is bone stock. They order the part and a week later I get a new fuel pump. Start driving the car back to work and the light comes back on. Take it back and now they said it is the O2 sensor. After waiting another week for this part to come in it gets put on the car and i take it, make it a few miles from the dealer and it come BACK ON. They said they called mazda to help with diagnosis and i need a fuel injector for cyl 3 which is getting a random misfire code. Wait a week, get injector on, drive away light comes back on.

So now I've got a new fuel pump, o2 sensor, and #3 injector all under warranty but the fuckin light is STILL ON. Like i said the car is stock, when it idles it sounds like it misses on occasion like hummmm putt putt putt hmmmmmmmm. I would take it to another dealer but there aren't that many speed authorized dealers in my area. Anyone have any suggestions? or experience anything like this? I've taken my car to the dealer once a week for over a month now and they are just shooting in the dark I think.

tell them if they don't fix it on the next visit they are going to meet your craziest friend

[curtspeed6]

what is the code that your getting exactly? and i would imagine its the same code everytime?.. How many miles on your car?

[ganque]

Sounds like one of the injector lines / fuel rail is blocked. All your issues are related to gas somehow.

[integrrac]

Well the Fuel pump issue, they were actually able to show the PSI was well below spec so I'm sure that was an actual issue and i'm not sure which engine code fired for that visit. The rest of the visits I believe are just Misfire on Cyl #3 and they used their idiot proof dealer flow chart to blindly replace parts until the issue goes away.

I'm not crazy worried about this for now since i'm just getting free brand new parts put on my car. It is getting tiresome though going to the dealer weekly.

[integrrac]

HAHAHAH Low compression on Cyl #3 and they want to take the head off. No rental cars avail for another 2-3 days or something so I get my car back tonight and have to take it back in to have the engine torn down.

So glad this shit happened before i modded it, and before the warranty ran out.

I should have saved up for an Evo.

[SSinstaller]

If the compression is low they need to do a leakdown test to find the problem, or just get you a new longblock....

They're not going to rebuild your motor, tell them to stop wasting your time..

[superskaterxes]

agreed just get a new motor. thats a common problem on this car

[integrrac]

The dealer guy said that's what he would rather do that go through the trouble of finding which specific part failed. I guess since they involved Mazda a bunch already in getting to this point he doesn't have the evidence they want to just straight replace the engine. He said it would be better if it completely blew up before i get it back in so there is no guess work and he can just replace it. I guess the plan is to take the head off and either they can easily see a failed part they can replace (not likely) or they can't see any glaring issues (likely) or there is some crazy issue that is not an easy fix (kinda likely). In the last two likely scenarios i get a new engine! I don't think they plan on rebuilding it at all, the tech just wants to have ammunition for when they go to mazda and say ship a new engine to us under warranty.

knowing my engine was about ready to blow would really bug the shit out of me.

why is it #3 cylinder is always seems to be the one that goes?

I think it would normally bug the shit out of me too but the dealer really seems like they are down to fix it and it hasn't cost me a dime yet. it would be interesting to find out where exactly all of these #3's are leakin.

If your stock and they want you to tank the motor, run the tank down to E, go put five gallons of 87 in it, get on the interstate and hit WOT at at 1500 rpms over and over--that'll finish destroying #3 for them...

Then top the tank off with 93...

Be sure you have the number for a good towing service before you do this...lol--If it blows be sure to turn on every accessory and kill the battery before it gets to the dealer.

[integrrac]

Believe me I've considered it.

Also in case anyone was wondering I bought this car with 27k on the clock so i don't know how it was treated before i had it. The trouble started recently just as the weather got cold and there are now almost 40k miles on the odometer.

[broncojd78]

probably belonged to a forum member who beat the shit out of it, saw everyone else blowing up, then panicked and dumped it on an unsuspecting dealer.

i would do what was suggested earlier. put that bitch in 6th and repeatedly floor it at low RPMs. hell, you might even do circles around the dealer when doing it. circling like a buzzard.

[integrrac]

I have some questions, if anyone else that has had their engine's replaced could chime in that would be great.

What is included in the engine swap? Is it just the block and head? Or is it a complete drop in with the turbo and all?
Where can i look for some recommended break in procedures?
Will a power train warranty be reset to Zero with a new engine?

The swap will most likely be just a longblock assembly, but I have also seen my local dealer swap the entire engine assembly--so it could go either way for you...

As for break in, just vary the speed and rpms for the first ~5 miles, then take it on the HWY and get up to 70~80mph(no WOT just part throttle up to speed) and then engine brake down to 45~55 mph a few times.. That should seat your rings just fine... After that the motor should be good to go, but you will still need to wait ~500 miles before you really get on it if they give you a new clutch and flywheel..

Your drivetrain warranty will not be reset, but if it's about to go out, you should still be covered on the new motor for at least 12K miles or one year...

[shpankey]

^^ wise advice

[integrrac]

FINALLY got my car into the dealer, driving around some shit Hyundai for the time being. They are doing a leak down test and tearing shit apart looking for a problem. I am on the edge of my seat waiting for them to call me and tell me some good news.

[Fa5t]

Huh, I'm curious in hearing what they find as well.

[ganque]

Good luck with it

[integrrac]

Still no word on what the issue is.





Stoppin in today to grab some shit out of the trunk and snapped these.

This is great. How to kill your engine by SSinstaller.

This is a whole new level of "How-to's" here.

After the dealer tore down the engine they weren't able to find anything that looks obviously wrong. They reported it to Mazda and are "waiting for a decision". Which i assume means i'm waiting for them to approve a new engine. If I get a new engine I'm going to probably clean the car up and try to sell it. Hopefully with a new engine I can get enough for it to get myself a nice down payment for an evo or something that isn't going to blow up. Sucks cause i love this car, love the way it looks, drives and handles. I'm just not interested in something so unstable.

A local shop near me is almost making 400hp with 272 cams, FMIC, and 1000 cc injectors, on an EVOVIII on the STOCK TURBO. So done with this car.

[integrrac]

Mazda requested service records! Hopefully this is a good sign.

The longest lull in oil changes was 3900 miles. I don't think 900 miles past 3000 is a HUGE deal, anyone think they'll give me shit? Other wise i've had the car since July so I've only had 3 oil changes.

How much do you think I could get for a 2007 MS3 with 40k on the clock and a brand new engine?

[integrrac]

New engine warranty authorized! Dealer said it should be here in like a week.

[Lex]

Did they ever speculate why it lost compression? Sounds like you had a leaking or stuck injector.

The injector on cyl #3 was replaced a month or so ago as one of the fixes for the CELs. I pulled away from the dealership and 3 miles down the road the light came back on. Took it back and they did the compression test and found low compression.

Before they replaced the injector they had to order it which took a week, they told me to go ahead and drive around with it "broken" (not sure how how it was broken or how they determined that from CELs). I expressed to them that i didn't think driving around with a broken injector was safe (running lean on one cyl?) they said na it's cool just don't get on it too much cause it's still working just not completely. Maybe that's why i ended up with low compression in the end, if the injector was leaking for a week maybe it was just spraying tons of fuel into the cyl. Though the car was running just fine except at idle.

Then again maybe i had low compression for the past 4 months and that was causing all of the CELs and they replaced the FP, O2 sensor and the injector cause they couldn't diagnos the real issue.

p.s. i asked what they would do with my block and they said that mazda takes those back for analysis.

Great to see they are putting in a new engine. Consider your dumping of the car carefully. With a new engine you basically have a brand new car. And because it's new your warranty time should be extended.

EVOs are pretty sick, indeed but I'm pretty certain they have their own set of problems. Each monster has a different face.

Keep us posted.

I probably won't go with an EVO, i'm just saying people are banging their faces off the wall to hit 380 hp with these cars, my engine lost compression at 40k bone stock. Props to all the mad scientists out there going for bigger power on this platform. I completely understand you gotta pay to play but the chances of having to pay with this car seem extremely high to me and I have student loans i should have been taking care of anyways. With a honda/240sx/evo there are just less unknowns and stronger stock engines and control systems. I'm still a huge fan of this car, the way it drives and looks and stock power levels, maybe i'll pick up another one some day when Mazda puts some attention into the weak points.


I'm sure there is someone on these forums that would be interested in having a 07 MS3 with a brand new engine. Once i get the car back I'll just have to see about it.

[integrrac]

Might be back in the ride by monday or tuesday, thank god cause this hundai peice of shit is buggin the hell out of me.

[integrrac]

BUAHAHAHAHAHA

So i stopped down today cause i was driving past after lunch. It was suppose to be done on mon or tues so i figured it should be close. Apparently they got the engine in today and started it up and they said it sounded like there was ball bearings in the engine. They shut it down and ordered ANOTHER FUCKING ENGINE.

Service guy said that he saw the same thing happen with another speed engine replacement. I asked if the turbo was alright or if it came apart somehow. He said he wasn't sure but the new engine is going to come with an intake manifold and turbo too i guess.

So another 3 weeks without my car. SWEEEEET

[broncojd78]

on the bright side you get a new turbo that (hopefully?) won't be as likely to smoke, right? we're looking at the bright side here?

On the downside i'm making payments on a car I can't drive and don't even want anymore. Seriously though, how do I managed to have a zero mile engine grenaded. The dealer tech thinks there is something in the intake mani that fails and gets sucked up.

[free_refil]

This is bonkers... I can't believe that a brand new engine would be bad like that!!!

honestly at this point, I don't find any of this THAT surprising, this engine is a joke.

[SSinstaller]

If they had it sitting out like that with all the ports uncovered, who knows what kind of crap could have fallen in a cylinder...

[integrrac]

It was covered, they let me snap a few pics though and covered it back up with a couple clean shop towels.

[shpankey]

Wow, remind me to never let you drive my car. Your luck sucks. lol ;P

[integrrac]

just a quick update while i'm thinking about it.

I"m still speedless, car and 2nd new engine are at the shop and they are taking their sweet time putting in this one.

[shpankey]

Don't feel bad. At least your on the positive side of things. For me, I just went into the scary unknown land of 130psi compression on all cylinders!

So this is what it felt like to be you back then. lol. This does suck.
