First, I have read and followed the Surge Idle Checklist multiple times. Yet, I still have the hanging idle (1600rpms) that is always temporarily fixed after an ignition cycle. Because of this, I'm almost certain its an issue with the TPS.
The following has been replace or cleaned in the last 4 years:
TPS sensor is one year old (3rd overall).
IAC is 2 years old (2nd overal).
TB is 1 year old.
10 pin connectors have been cleaned and spread/closed 3 times.
TPS connector has been cleaned and spread/closed 3 times.
Plastic vacuum lines replaced.
New PCV valve, grommet, and filter.
After all parts replacements/trouble shooting..the idle has been reset using the proper method.
Cleaning the 10pins and TPS connector seems to work....for about 6 months. Then the problem returns.
I'm thinking it's one of two possibilities.
1) Harness problem? The car has 160,000 miles and I'm beginning to think all the intake installs (3) has possibly broken a brittle wire in the engine harness.
2) The multple cleaning and spreading of the 10pins and TPS has fubar'ed the terminals. Is it possible to eliminate these cursed connectors and solder the wires together? I'm learning toward doing this anyway. I love the thought of never dealing with these connectors again!!!!!
I'm at a loss and was hoping the Stangnet community could offer some insight as to helping me find the root cause and a permanent fix.
