I have been throwing code p0171 for the last 5 days. I need help figuring it out. What did you guys who threw the code do. Ron has put up some tips on what to do. I did some of them, I am looking for more information I guess.
The car runs crappy at idle, there is a sound like it is about to die. i need to give it gas at lights sometimes, the idle sounds like the engine is running out of gas. It seems the cable to the throttle body is loose. I pull the throttle a bit towards me as i am standing over it. It stays at the higher level.. where it sets. The engine will sound better for a little. I will try tightening the cable at lunch.
Ive done so far:
1. cleaned out throttle body and cai.
2. pulled off egr, there is a LOT of carbon buildup. I cleaned it as much as I can and put it back on. I did not hear any noises or anything else from it. I am not replacing at the moment because my dealership wanted $210 for a new one.
3. Changed the pvc valve.. mine was dirty
4. reset the battery.
5. Checked the spark plugs, they are pretty dark, but also pretty old.
6. Checked all connections except for hard to reach. did not check the o2 on the headers... this could be the issue.
Would a pcm update be able to remove the first bank o2 sensor, the one on the headers. I will ask beyerch tonight.
What else needs to be checked out. My car is still running like crap
thanks,
