SES code P0171

Nitex · 03-25-2010, 02:35 PM

I posted over in the engine tech area but i figured i would put my findings over here in the Intake/Exhaust area.

I threw a CEL/SES (service engine soon) last weekend. My idle was hanging at 1.1k and would not go below. I took it to my mechanic today and had him run the code, which came out to be a P0171, which he said was a lean code. We looked at my gen 3s and couldn't visually see any areas suspect for vacuum leaks. We decided to just reset, and address the issue again if/when the CEL comes back on.

If anyone has had an issue with this code i would appreciate hearing about how you fixed the situation.

If anyone wants to hear what it sounds like here is the link to my youtube video, off topic but oh well! I still need to post my install pics and thoughts on the setup.
