idle stuck at 2k
I have an 88gt with a powedyne (i know i know) supercharger, edlebrock heads and edlebrock intake on it. its been sitting for a while and i had a new top put on. I drove it home yesterday about a 90 min drive. Half way home i slowed down to make a turn and the rpms stayed at 3000. I turned the car off and back on and was fine. after getting home i started it back up and now the idle wont drop below 1500. sits at 2 for a while and then dropps to 1500. didnt hear any vacume leaks but it was to hot to go searching. any ideas????
