Hello there,
So, I've got P0171, car runs very well when cool but once it warms up it does lack a bit of power. Rough idle is almost non-existant, if I stare long enough it might move a hair if any over a period of a minute.
Quick background that might help:
- Recently installed new vanos seals which greatly livened up my car's driving capabilities. Not soon after that I got two codes P0491 and P0492, I quickly realized that I had torn the vacuum hose that connects to the secondary air pump. No problem, got some new hoses on both ends, then drove 500-600-ish miles all the way through part of Canada and back into the US. It wasn't until right when I hit U.S. border patrol that I got a CEL and P0174 (Carly adapter (INPA almost) states "Lean Deviation Banks 1 & 2). Now, I cleared the codes and drove just a few miles (just after border patrol) before the CEL came back, but this time I got P0171 and it's staying in Pending codes (not stored) as of right now.
Didn't have much time to really look things over today, but I did notice my O2 sensor wires (on the exhaust side by the headers) were hanging down and I had read online that they might have overheated. I've readjusted them back into place and will see if it gets any better.
I've rebuilt the DISA a year ago, new MAF two years ago, all intake boots look good, clean TB, clean ICV, new VCG (700 miles ago), fuel filter 3 years ago, all other vacuum hoses look good, F-connector is good, CCV is coming up on 2 years old now)
EDIT: The O2 sensors that I had noted were hanging down were replaced a year ago and I hadn't noticed any plastic melting, so unless it can be damaged other ways I'm sure they'd be good.
Any ideas on what else this might be?
Thank you!
