Michael Savage Posted February 16, 2015 Report Share Posted February 16, 2015 Recently changed the fuel filter it was dirty and had some ethanol sludge in it. About a week ago. Haven't done anything else. Cracked it today and it had a consistent miss hooked up the scanner and it didn't detect any misses. Was wondering if someone could take a look at the readings.

Michael Savage Posted February 17, 2015 Author Report Share Posted February 17, 2015 Located a vacuum leak where the TCE EGR Adapter meats tge intake, lucky me they didn't send me an extra 6MM Hex L- wrench and mines stripped. But if anything looks funny on the scanner let me know. Haven't used it in a year and I forgot what the last good readings were Quote Link to comment Share on other sites More sharing options...
Schurkey Posted February 17, 2015 Report Share Posted February 17, 2015 O2 cross-counts? If that engine was misfiring, I'd expect the fuel trim to be driven rich unless the O2 sensor was so lazy it didn't react to a random misfire. Quote Link to comment Share on other sites More sharing options...
Michael Savage Posted February 17, 2015 Author Report Share Posted February 17, 2015 Fuel filter was gummed up terribly when I changed it so I was probably running lean for about a year so it could have been a self tuning issue as well as being rite at sea level now hasn't done it again and fixed the vacuum leak I found. It's a 95-2003 nodded 3100 Quote Link to comment Share on other sites More sharing options...
