SES on my 2004 Oldsmobile Alero.2.2 liter.
The vehicle was just in a front corner collision. Changed spark plugs.
Question: I just had a collision in the front driver side corner of my vehicle, everything is pretty much cosmetic, but after the collision the car started idling funny, and lacks power when i push the gas and is really hard to start in the mornings.
Went to Autozone and the guy said it was a mis fire code, and to change my spark plugs and it would fix it, i did, and it did nothing. Is there a sensor or something that could make the car act this way? That could have possibly been messed up in the wreck, thank you so much.
The damage really should have nothing to do with it. Nothing on that part of the car to cause misfiring. You may want to get it scanned again and note which cylinders are missing, and if possibly another code or more.
Two common things that cause this condition on the 2.2L are the ignition module, or the ignition coil housing cover (shell). Normally 2 cylinders will go out at the same time because the internal circuits fire 1-4, and 2-3 as a pair. That would explain the no power, idle, and hard start. It does sound as if you are running on only 2 cylinders. Not something you just want to put a part on and hope it fixes it, it will need to be diagnosed by a good technician.
Let me know if you need further assistance.
2001 Oldsmobile Alero 2.4l service engine soon,trac-off.
We changed plugs,boots,and car runs good then boom runs rough then boom runs good again housing,oil change. Car runs rough at times, then goes back to normal. What can make this happen?
You could have a loose ground connection. We have seen this several times. It is 2 small black wires on the transmission housing near the coolant fan. Have the fuel pressure and ignition module checked also.
