I took my car to a shop to have it put on the dyno to verify some claims and documentation the seller had given me. The car is totally messed up...afrs climbing toward 15:1...all of the documentation he had given me is a complete fraud. Everything the mechanic had reported to me at Puresports is completely invalid. This is RIDICULOUS!!

I will be going after him legally. In the next week or so, I will be filing the case.

This has me pretty pissed.

To further test the ISC, you will need an ohm meter. I believe it is supposed to generate 5 ohms resistance to be in proper operating order. The FSM explains how to test the ISC.

Where are you in AZ? Maybe we can get together and see what is going on with this car?

If you disconnect your Idle Speed Control your RPMs ought to jump up to 2,000- 2,500 and the engine ought to hunt .

Your ISC is not working. Either because the solenoid itself is shot or because the sensors feeding info to the ECU, either the coolant temp sensor at cold start or the O2 sensor after the car is warmed up, are not working properly.
