Engine Performance problem
1994 Ford F150 V8 Four Wheel Drive Automatic 248000 miles
The problem started with the check engine light coming on. I ran the codes it came up 172 O2 sensor lean. I put a new one in, erased the code. Came back on after a few minutes. The truck has been runniing rough, feels like it wants to stall. Driving on the highway, the CEL finally went off. Thats when I started losing power, Stepped on the gas and heard a popping noise. The check engine light came back on, the truck ran fine again. It did this for the trip home. Hooked up fuel pressure guage, all withiin specs. Cleaned the MAF sensor. Could it be the fuel injectors are dirty?
have the same problem?
