I'm out of ideas.
The car runs with an elevated idle speed of about 1400rpm's.
I've replaced the TPS and throttle body.
I've checked water and air temp sensors
The ISCV seems to be working since the idle is very stable.
I've checked for leaks with start gas.
Lambda (O2) sensor was replaced this winter as part of another problem.
What else is involved in idle speed control?
