Michael Savage Posted February 16, 2015 Report 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. Quote
Michael Savage Posted February 17, 2015 Author Report 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
Schurkey Posted February 17, 2015 Report 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
Michael Savage Posted February 17, 2015 Author Report 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
