Greetings all, I'm new to the forum and have a question that I hope someone has encountered before.
I have a 95' with a high idle (1700 rpm), hooked up the OBD and it said TPC had a voltage problem, replaced TPC.High idle remained.
I saw a couple vacuum lines that were starting to dry rot, thought I might have a vacuum leak. Replaced all the vacuum lines. High idle remained.
I was told to check the IAC, opened it up and the diaphram was cracked, replaced IAC. Idle jumped to 3000 rpm.
I have cleared the computer and am at a total loss on what could cause this, I spoke to two mechanics that have no idea, I am hoping some here have seen this problem before and would share a soultion.
