Engine Mechanical problem
1991 Ford F150 V8 Two Wheel Drive Automatic 490000 miles
I recently bought an old F150 with the 4.8L motor. I took the truck to emissions and it passed everything except hydrocarbons in idle. The truck is running real rich because there is a strong gas odor. The limit is 220 and mine is 1235. Is it a faulty oxygen sensor? I just replaced the water pump, plugs and wires, and cap and rotor. The truck runs solid but rough. I am a single mom and have no clue where to start. I took it to Meineke and they said it was the EGR but they also charged me for work they never performed. Rip offs! Could it be the EGR? Any help would really be appreciated. Thanks!
have the same problem?
