i drive my car for few hours and the engine check light comes on. it throws the code 1 which is 1st o2 sensor. but when i turn my car off and back on the check light goes away. is that mean my o2 sensor is bad or going bad or my car is running too rich that after driving for a while that the o2 sensor gets cloged up? or is that even possible? what you guys think. i dont want to just replace the o2 sensor and have the same problem later on again. thanks.

 

Keep driving it to see if the o2 pops up again. COuld of just been a loose wire.

 

i did it keeps coming on but not for while though like i have to drive straight 3 hours and it ll come on type of thing.

 

Hmm try cleaning your motor with some seafoam.

 

whats a seafoam and how do i clean my motor with it.
