p302
hello guys pulling my hair out on this one have 2003 1500 with the little 4.7 changed plugs and coil for number 2 reset engine light light stayed off for a week now back on anyone else run into this ? if so what did you do to fix this have only 39000 miles thanks
So you got misfire codes right? You changed the plugs and you swapped the #2 coil with the coil from another cylinder right? Check all the electrical connectors and grounds. Is there any play in the valvetrain assembly?
yes you are right but repaced the coil pack with a new one and cant find any play in the valve train 125 compresion in all cylinders,only 40,000 miles ,seam to think its fuel related , anybody can tell me how to check the fuel press over night and what it should be thanks
I just had my Impala SS throw a p307 which is a number 7 missfire and it ended up being a weak injector. I replaced, plugs,wires, and the coil and STILL ended up replacing the injector. Good luck
