Default 07' runs fine till CEL comes on,then hesitates.

Hello,my neighbor has a 2007 CX-7 with a rough idle and it runs fine otherwise UNTIL the CEL comes on. It then immediately starts having hesitation issues. It has 100,000mi and it recently had it's first CEL light showing a p0302 code. Plugs were all lean,gapped them to .027 and the rough idle improved. Switched the #2 coil with the #1 ,no change. I figure it's probably the #2 injector causing the hesitation,but would that cause it to run fine until the light comes on,then immediately start having hesitation issues? Also,I cleaned the MAF sensor,new air filter,gave it a SeaFoam treatment,checked all fuses and grounds.Any ideas?
