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.

Pick up generic vacuum lines and replace the problem area.

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.

Got it. I replaced all the vacuum hoses that I could see while I was in there, they were all rotting and about to fall apart.

Common problem.

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.

Double check all vacuum lines. It may also take a little time to relearn the fuel trims.
