Q&A

Check engine light on-intermittent start-slight jerking while driving-rpm erratic. Check engine light on (O2 sensor P0134 code-lean issue) & car would not start after a long trip (otherwise has been ok). It was cranking but no fire and battery was ok. I got it started with carb cleaner in the intake. Spoke to a diognostic guy that said replacing the sensor would not help. He suggested testing fuel pressure (can't find where to thread tester to) & fuel flow. Any suggestions, how and where to test each to find exact problem? I wanted to fix the problem before selling it. The car has been great to me at 143000 but I am selling it for an SUV.
