Ok guys ive been having a prob with my truck for sometime. First it was the fluctuating idle and shutting off at stops. I think i got that prob fixed, by cleaning all the carbon in my intakes and a number of other stuff. Now the prob that im running into is that, when i drive my truck it hesitates when i accelerate it. Im think it might be a fuel pump prob? Could that have cause the shutting off at stops too? Are there any signs of a fuel pump going out? Any ideas?
