*Corrosion or poor mating terminals and wiring

*Damaged PCM
Fuel System
*Excessive fuel pressure
*Leaking/contaminated fuel injectors
*Leaking fuel pressure regulator
*Low fuel pressure or running out of fuel
*Vapor recovery system

I just went through this same thing with my 91 Explorer. Changed the sensor(original) and my mechanic drove it for two weeks to see if the check engine light would come on again. It didn't untill my wife drove it home and it came on and idled rough. Took it back and discovered the fuel pressure regulator was shot. It was so intermittin that the light was off when I drove it back to him untill 2 miles from his shop and then came on. But the engine was idling so smooth when I got there You'd never know anything was wrong. Had it hooked up and saw the fuel pressure jump from 32 lbs to 75lbs. and back again.
