[95twinturboawd]

When we started the car the idle was fine but as we drove the car it became progressively worse. Then by the time we shut off the car it was up to 3500 rpm in park. The throttle body has been taken off and cleaned plus a new ISC

Inspect ALL vacuum lines and perform a boost leak test. Also a fiav that is failing will cause an abnormal idle.
