1991 Ford F-150 Repair Question
Mileage: 145,000 miles.
Will a bad O2 senor cause a vehicle to die at stops or while idling?
Answer
the 02's could cause a stalling problem.but i could be of a lot more help to you if you post the code or codes and engine size.then i could give you a much better reply.
I was told the code was 41 and it is a 5.0 engine.
code 41 is basicaly a " blanket code" it is a fuel control code and could signify a rich on lean condition,depending on whether you scan it koer,or koeo,which just mean key on engine off or key on engine running.it could be caused by an o2,or the map sensor or the fuel pressure regulator,ect.your best bet would be to have it diagnose at a competent shop.it cost to much to guess at it.
Thank you so much for the information.
I replaced the O2 sensor, fuel pressure regulator, and the MAP sensor but it is still dying on me when I come to a stop or at a very low rate of speed. Please help...
