Okay, i know this is going to sound dumb, but i really don't know what's going on. when i start my rig for the first time each day i let it warm up for a good while. then, i hop in, put it in first and start driving. then as i'm just about to shift into second, for no apparent reason, my rig feels like a rocket flew up it's butt and i'm flooring the accelerator. the RPM's soar and i'm all of a sudden driving much faster in first than i would like to go. then, as quickly as it started it stops and doesn't happen again until the engine is completely cold. seems really bad for the engine and i don't like any rapid random acceleration. can anyone tell me what the **** is going on? it has a turbo and a 5 speed if that helps. the accelerator does not feel stuck. its more like the engine snorted a load of coke.
