Well here's the problem, with the engine already warmed up I come back to start the truck and its starts up quickly but then it surges back and forth from 500 to 1000 rpm. It sounds like the motor is going to quit. If i tap the gas a little it levels out and idles fine then. My gas mileage seems to have gone down a lot lately to, I'm not sure if its a vacuum leak or the fuel regualtor is bad. Any ideas??
 






Sounds like the IAC valve.
