Idleing starts fine but when it finally gets warm it seems to want to hesitate from low to high and not stay steady.. It also has a problem keeping volts up when it is put into a driving or reverse gear...but I will win.
Anyone have any Ideas.
Does it have the idle mixture solenoid in it? Is it the carb that came on the original engine? Do you have the computer hooked up to it? What cam does the engine have in it? Does it have at least 16 inches of vacuum at idle? What other modifications have been made to it? Does it have a vacuum leak? Is the timing set right?
