while i was driving i put my car into neutral and coasted for a while and the rpm's sat 2k and would not go back down until i was at a full stop, then they went to about 1k instead of 900-850. also if i put the car in say 6th at 40 and the rpm's dropped real low, then i took it out of gear, the rpm's would go back up to 2k. i think this is a sign of a vaccum leak, but where do i begin to look? im lost!

 

problem solved....had to do with the AC system, which someone who was riding with me had turned on, but i tuned the car without it, so i guess that was the problem.....feel free to delete the thread

 

Do you use HPTuners?

 

no i dont....it was tuned with ls1 edit
