This is what i got

Cel#
12-(ERG) Exhaust gas recirculation lift valve
41- Primary Oxygen sensor heater
48- Lean Air fuel Sensor
71- Random misfire Cylinder 1
72- Random misfire cylinder 2
73- Random misfire cylinder 3
74- Random misfire Cylinder 4

FML!!!

Anyone have any clues on how to Fix 71-74?

 

I cleaned my IACV and now my car dies when i push the clutch in to coast (i.e. to turn or something like that.)


I parked it in the driveway and let it idle, it's idling right above zero. What could cause this?

 

CEL's 41 and 48 sounds like you have a bad oxygen sensor. A random misfire can come from fouled spark plugs. Check each and every spark plug for carbon damage, resistance and voltage.

Another source may be the fuel injection system. Make sure that your injectors are not dirty as this could cause a lean air to fuel ratio in all four cylinders. Also check fuel pressure. Do not rule out "bad" gasoline as this can also through off your fuel injections system.

Lastly, check your overall compression as there can be leaks in a headgasket etc, that can be causing the random misfiring.

Bump for someone with mroe excperience.

 

Thanks, we have had bad gas around here lately, but my check engine light has been since before the bad gas. I will check everything else you mentioned above and update.

Anyone else have any other suggestions? Especially on my second post?

 

Clean out the EGR valve port and passages, and I think most of the codes will go away.

 

Werd^ Thanks RJ. That too

 

I will get to that on Wednesday, Any other suggestions? The ones provided are great.
