for 10 seconds. If I disconnect battery, come back to it in a day or so, the ISC plunger will come out to fast idle, as it warms up, retracts to Idle. As long as I don't turn key off, ECM commands ISC fine(A/C etc.). Turn key off and ISC plunger comes out to fast idle and stays there. Replaced complete engine wiring harness, ISC motor, 2 ECM's. Adjusted min. Idle, max. Idle, and TPS. Any ideas? Thanks
have the same problem?
