Idle problems on evos can suck dude. I had a problem that would be random where the idle would go north of 2500rpm. It would make me upset and ruin my day. Found out it is code related with my ECU, possibly from overflashing, a logging malfunction that occured, or from an old flash that I got over two years ago no longer in use except for some remaining bad code.

I got fed up and totally deactivated the entire idle system on the car, blocking the idle bypass, removing the stepper connector, then adjusting with BISS. Now, except for cold starts, my car has never idled so consistant since I bought the car with 18 miles on the tach 4 years ago. Stays at 850.

Check the PVC for blockage, that can make it stall, and don't touch the factory set BISS unless you absolutely have to

 

anyone els with a ix have this problem
