Engine Mechanical problem
2002 Ford F150 V8 Two Wheel Drive Automatic 54,000 miles
Hi, and thx for having the time to ask my question. I have a 02' Lighting that I bought used. Since I had it the truck has been running rich. I know for a fact that it has a after market exhust and that one of the pulleys on the belt has been change. Also I replace the air filter to a BBK cold air system. I took the truck to several shops and there saying that the O2 sesors are reading rich, banks 1 & 4. I was going to buy a flash tuner to change the PCM and get rid of the check engine light off but would that fix the problem? I need to fix this because I have to take my baby back to inspection by June. THX
have the same problem?
