My Dad owns a '96 GMC Sierra with a '99 350 and rebuilt trans. The engine has about 70k miles on it, and the truck has a new battery. The truck starts up every time very easily. However, after put in drive, when you step on the gas the truck wants to die out and stall unless you let off on the gas. After the initial take off and the truck gets underway, it no longer does this. If you park and restart while the engine is warm it does not do this. Only seems to be when cold. He tells me that the voltage gauge seems to be a little wacky, but I doubt that an alternator could be causing this. Anyone have any similar issues? Any things we should try? Fuel filter? Please help. Any help is appreciated.
Thanks in advance,
