We have a high idle problem. Have changed..iac valve. Throttle position sensor, EGR valve and purge valve.

Cleaned the throttle body and placed a new gasket. Have sprayed carb cleaner to try to find a vaccine leak. We're running out of places to look! Can you think of something that will help?

Could be a bad idle air control valve (iacv).
When these go bad it will compromise your idle. Also check the accelerator cable if it gets hung up or moved from the holder it will give you problems. Also, I would check your throttle position sensor - some are adjustable to raise or lower the idle.

Finally, I think you mean 'vacuum' leak and not vaccine?
