Hi everybody, today i turned my car on for the first time in two weeks (just got back from vacation) and when i started the car everything was fine then all of a sudden the tachometer needle goes flyin up to 2000 rpm then back down to 1000 then back up and it continues to do this i tried driving around the parking lot and the car would periodically jump like someone was pressing the gas. i dont know what is wrong the car was working perfectly fine before i left...could it be that since i did not start in a long time that somethin got messed up? thanks

could be a bad iac motor (idle air control)

or even your voltage could be bouncing around a little causing faulty sensor readings to the cpu

also you may have a mis fire and when it surges thats when the injector or plug starts firing

just a few good luck [Wink]
