Hey y'all
I was driving yesterday, and got ce light and some codes. The car was stumbling really bad at around 1000 rpms, and light throttle. It seems fuel related. The fuel filter is about 1 year old. I pulled the codes by grounding the self-test lead, and the codes I got were:
539 something to do with ac
176 lean condition on left H02S
177 rich condition on left HO2S
524/543 Low pressure fuel pump relay
Anyway, I did a consult with my bro who is a technician, he told me that it is probably something electrical, and to pull the fuel pump relay and replace it with a different one. I was kind of in a hurry this morning, and I didn't have the manual showing which relay was the fuel pump, so I just wiggled 'em all. On the drive the ce light didn't show up. It seemed to stumble a bit, like maybe starving a bit for fuel. What do you folks think? My next move will be to replace the fuel filter, check pressure with a gauge while driving around. And maybe do some diagnostic tests on the relay/fuel pump system electrical area.
