What is this vacuum hose and where can I find one?
I was greeted this morning with a P0171 code. I now know why my long term fuel trims have been so high, today they were pegged and the STFT was all over the place. I hope this explains why I have so much KR, I suspect the engine has been running lean because of the unmetered air.
That is the evap purge valve to TB hose. I find a small length of 3/8" line, then an adapter from 3/8 to ...uh something smaller works well and then use that smaller hose size to connect to the evap purge valve.
The whole thing that got me started looking at vacuum hoses was a LTFT that'* pegged at 16. It'* down to about 12-13 now, but I still think that'* too high. Is there anything else I should check, or is this considered normal? Seems like the car is running lean.
