A few days ago, I posted in another thread about my 2000 4runner and its check engine light. Anyway I started this other thread to once again call attention to it.
The code is P0171, which shows my air/fuel mix to be too lean, and these are the possible causes, according to the list I got from Autozone:
1) Low fuel pressure
2) Faulty MAF/VAF sensor
3) Cylinder misfire condition
4) Faulty HO2S/AF sensor
5) Large vacuum leak
So if this helps anyone with the diagnosis, let me know. I'm thinking it's the MAF though, after reading some online tips on how to clean it. I looked at it and it looks dirty. So if you have any tips on doing so, please let me know!
