Was driving home last week and engine starting sputtering. Made it home.
After re-starting, idle was extremely high. After reading some notes here, I replaced the IAC (Autozone $50) and that fixed the idle issue.
However, now, the engine still runs rough. Seems especially so if I try to speed up quickly. I also started the car, put it in drive, and pressed the brake and then put the AC/HEAT on. Engine began to idle very poorly.. did not stall, but shook like it could have. Turning off AC/HEAT returned idle to semi normal. When driving, on the highway it appears the engine runs fine after getting up to speed.
Autozone codes were P0316 and P0301. Any assistance is appreciated!
P0316 is Misfire Decetected 1st 1000 Revs
P0301 is Cylinder 1 Misfire
Check and replace Spark Plugs,Wires and ur Coils (If short on money, just replace the first Cylinders plugs... I did it to my firends Maxima not to long ago Coils and plugs where terrible, wires where okay though)
Well, I replaced the plugs yesterday, in the dark. That was fun. ;-)
Anyway, test drove this morning and it appears the coughing is gone.
Good acceleration, etc. Used Bosch platinum plus plugs from Autozone (2.99 each).
The engine light is still on. Does this mean there still is a problem? Or do I need to reset it somehow? Autozone won't do it anymore. Tell me its agan' the law.
Shouldve used motorcraft or autolite plugs. Bosch have proven problematic in the bulls. If you dont have a code scanner or reader, simply disconnect the negative (ground) battery cable for a few minutes.
