91 ford ranger 2.9
The other day on a 3 hour road trip the check engine light came on for 15 minutes, and then shut off for the rest of the trip. While driving the other night it came back on; no real loss of power just seemed to be a slight "caming" effect at idle. I ran the obd1 self test on it and got codes 67 and 41 with key on engine off. 67 is something to do with the clutch pedal ...and irrelevant for this issue I believe. 41, However, says something about "HEGO sensor circuit indicates system lean (right side)." From what I gathered it meant something about the o2 sensor...so I replaced it and now the truck has no check engine light BUT the truck runs WORSE. ROUGH idle, will die if I don't rev the motor, cab/motor bay smells like gas...with gas leaking from where the ds exhaust pipe connects to the headers I believe. Pulled a spark plug and its covered in gas as well (duh of course...just saying). I run the self test now and it gives me 11...which is system pass...umm no....I have checked for vacuum leaks, I don't have a way to test fuel pressure but I will note that a few days ago it started randomly busting off the L shaped fuel line plug on the top of the fuel pump lid....(forgot the clip but it never did it before, had it like that for a month). It has a new fuel pump, temp sending unit, o2 sensor, thermostat, fuel filter.
I REALLY would like some help, thanks
