I had to change the rear plastic tubing to the block because it broke. So I took it apart, fix it, and put it all back together again. Start the car and the car is revving at 2500 rpm. I think there is something that I did or didnt connect something right. If it has happen to any of ya before, PLEASE HELP. I paid Pep Boys over 500 to fix the same problem before. I feel so stupid taking it back to get fixed. Hopefully I can figure something out.
