My 1991 Isuzu truck has rough low idle on cold start then high idle
My 1991 Isuzu truck has low idle on cold start then it will move to high idle. Even if you punch the gas it won’t slow the idle. There is an O2 sensor light on. Sometimes, in warmer weather it will start and idle correctly but on most all cold mornings the idle is high. Once you get a mile or two down the road it will sometimes correct. Sometimes not. Lol. Ghost choke problems.
Ist dies eine gute Frage?
