[QUOTE="Roush2012, post: 1328344, member: 28517"] Well it did it again this morning. Pulled out of the driveway and noticed the o2 bank 1 was stuck lean. Drove it to work which is about 5 miles and about a mile from work the sensor started dropping and went to .649 and it started stumbling and wouldn’t accelerate. Like it has a misfire but it’s not. Then went lean again and stayed there. Pulled it in the shop and now I’m pissed. I unplugged the sensor and blew the connector out, same thing when I started it. Then I unplugged the battery took the pcm harness and blew that out. Same thing. Checked again for vacuum leaks. Then I pulled the maf sensor off and cleaned it out, changed the purge valve (just because it’s so common to cause problems), Did a fuel trim relearn, started the truck and bam sensors reading properly. Drove for about 20 miles and no issues it drove great and didn’t throw any codes. Now I’m not convinced the purge valve did it but who knows. I’m happy tonight guess I’ll see what tomorrow brings. The thing that gets me is p0131 came up again for o2 sensor voltage low. That’s what’s baffling me as to why the voltage is is being seen as low. If it continues it’s going to Livernois they are the geniuses that can figure it out. Btw if you don’t have a mycalibrator touch from them....it’s well worth it with the live data it can monitor Sent from my iPhone using Tapatalk [/QUOTE]
