2008 2.0 LNF P0302 Misfire when Cold...
My car has 92000K (57000mi) on it and I have the GM turbo upgrade kit. Everything else is stock.
When the car is cold it will idle on 3 cylinders for about 3-5 min then once it is warm cylinder #2 will kick in and it will run just fine. I just installed new AC Delco plugs (0.034), and I have swapped the coils around and the misfire stays on #2.
I have also put two bottles of GM Injector Cleaner (the $25 a pop stuff) and it has made no difference. (also changed the camshaft position solenoids when I did the plugs)
I just put my summer tires on today and it was the first day in 8 months of f'ing winter that I could actually build some boost and put the power down to the road. All winter I have never built any boost or hit WOT. (Forgot how much fun this car is)
Has anyone seen this before when cold at an idle?
Could this be an faulty injector or a sticking intake valve?
Not sure where to start and I don't really want to replace parts that are still good.
Thanks,
