Ok so I have a 99 z24 with 70000km on it. The other day I stopped at home for 20 mins and when I went to leave the battery was dead which was very wierd because I dont think anything was on and it was only 20 mins. I boosted it with an eliminator and when the car started it was like the throttle was stuck as it revved straight up to 4000 rpm and would not leave there...after a while the idle back down to 1000 rpm but now surges back and forth between 1000 to 3000 rpm. If i drive it on the highway over 2000 rpm then it is fine. IF i put it in gear with my foot on the brake then it idles fine...
Hope you guys can help becuase I cant think of anything here....
