Re: Haveing a on going issue
I hope you find the problem as I am very curious what's causing this. I had a chevy truck that did the same thing, I never did resolve.
I checked everything, including dropping the tank and cleaning fuel lines. My assumption was it was a vacuum line or maf. Never did get that far as I wound up trading it. Funny thing was it would run fine for about 100 miles after changing a fuel filter. So it ran good when traded... |
