Okay, so first Happy 4th!
Got the fuel pump swapped last night. It was running pretty rough before the change and after it started up and idled smooth. Felt good driving, no hiccups and acceleration seemed better. Didn t run the AC at first but did when got closer to home. Didn t seem to have any issues though it was in the mid 70's out.
Got home, stopped and restarted. I let it idle for at least 20 minutes. It did good at first then would start getting smaller sputters but not as bad as before and not as frequent. I ll see how it does when it s hotter out.
I plugged my scanner in to look at fuel trims at idle. I ll post the pics but my long terms were +13.3 and +9.4 and stayed at those numbers pretty much the whole time. I would give it gas and they would move a little and immediately go back to those numbers.
I also went in the test part of the scanner to see misfire counts and went in the O2 heater monitor test. This is after it was idling for a bit. B1S1 was at 77 F which was outside temp. B1S2 was 95F. B2S1 was 113F and B2S2 was 59F. Not sure if that s even important but found it strange the temps would be so different. The live data always shows both my Cat converters at the same temperature.
I also noticed that my thermometer in the car was reading 76F but my ambient temperature sensor on the scanner was reading 115F. Are these supposed the same?
