I have a 1988 dodge ram charger with a 318 motor with throttle body. It runs really good when I start it up and drive it for about a half of an hour.
But after that when I step on the throttle a little bit, it hesitates. If I let off a little bit, it will go or if I really step on it, it will go also, but if I just hold it there, it really hesitates If I stop, the idle jumps up and down so much it causes itself to stall. It seems to only do this at low RPM's. If the RPM's are higher it's fine
