High Idle 1989 5.7 TPI
Hey folks. So we were able to get our car running fine now. It runs great in open loop, idles at about 700 and lots of power. However, when it goes to closed loop and warms up, it jumps up to 1500 RPM. We did some research to try to find the problem. We found this forum post Surging at Idle - Third Generation F-Body Message BoardsSurging at Idle - Third Generation F-Body Message Boards and tried following the instructions on there. The car still has the problem of jumping up into high idle and it's a pain. Does anyone have a solution? Because I highly doubt any mechanics around me know how to fix TPI problems. Thanks.
