Ok, I have a 1993 manual 4.9l with 153,000 miles. Just this morning i drove my truck to work and everything was fine, I parked it and it sat for about 10 hours. When i tryed to take it out tonight it was messed up. Every time I would give it gas and shift and or just give it gas and let up off the gas the throttle and the speed would keep going. I could shift, let up off the clutch and not have to give it gas it would keep going and everything would be ok. After I let up off of the gas it keeps giving it gas for about 3 to 5 seconds then it slowly dies down. Does anyone know what this might be? I dont need this problem right now and hope it can be an easy fix. Thanks to anyone who can help, its greatly appreciated.

 

is the pedal also slow to rebound?is it efi or carb?lift the hood and have someone give it gas.see if a cable is hanging up if you have not already
