engine rpm surge. help needed.

put a propane torch to screw heads cycled hot the then cold can un stick them(trick)
ok 100rpm test that was good test, if hot engine, that means the IAC is closed and GOOD!, great testing on your part.
"REDACTED"the engine is strong to run at 100 most stall at 200.
but the tach is not very accurate and both numbers are good,. or near stalling..

at idle hot. no loads on alternator, AC off.
the ISC modulates at 50 % or 1/2 open. in fact it does that and holds 800 rpm like rock. even shifted to DRIVER. open more.lots more.

tell me more about what you did (all) to get to 100 rpm or 200.
what hot engine and.....????
tells me there are no leaks. (vacuum)


the question the becomes why is the ECU opening the ISC so much.
one way i did not tell you yet is the the wire to the steering pump, sensor
that tell the ECU the the PS power steering is overloaded and sends idle to 1000 rpm.

1 wire shorts to frame the bad deal.
I well send more data to you later today.


Ha. I think you mis-read what I said. 100rpm. I said unplugging the isc while running hot will drop my rpm by 100. Not to 100. I was just wondering why the isc would be commanded to raise idle if no reasons were present. Like idling in park hot with all loads off. I still have not blocked my iac valve to check if its working right. My fuel mileage is around 19mpg. But I do have the slush box 3speed. No working tcc lockup. And 31" super swampers set to 17psi.
