Check engine light
I need help with diagnosing a problem I have with my 1991 F150 5.0. When I start my truck the check engine light isn't on but after driving for a mile or so it turns on and i lose throttle responsiveness. Ive looked it up online and some sites have some symptoms mine has but no exact match. I'm thinking that it might be an O2 sensor or mass air flow but I am no master mechanic. Any help or ideas is well appreciated.
