Help. It show this code and then a misifre on #2. The first code I got a week ago was misfire on # 1. Change the plugs about 2 weeks ago. Kinda odd all on the same side of the engine.. Any help would be great.. The engine is running real bad like a couple of cylinders are dead.... mommas car ....well you know how this goes lol

Thanks,

Scott

I'd check to make sure the coil packs are all seated on the plugs by pulling them off and re-seating all packs on the affected side of the engine. Also, could be a bad coil.

Did you coat with dielectric grease before re-assembly? Check boots for damage.

Swap your #1 and #2 coils with #5 and #6 coils. Then if the misfire changes, you'll know the culprit.

If it doesn't move, you're looking at spontaneous injector issues or a head gasket problem.
