99 454 rough idle
My 1999 454 suburban idles poorly, it nearly dies sometimes but recovers.
It runs great at startup, cold, but after about 30 minutes, idles rough. It has 175,000 miles on it,1000 miles on intake gasket job, hoped that would the fix rough idle. New fuel filter didn't help. I think it may need injector replacement or maybe a knock sensor. No I haven't pulled a code yet... |
