I have a Gen 1 V6 5 speed. Car does not idle down when shifting into neutral and either coasting or coasting and braking to a stop. Idle hangs and bounces around up to 2500 RPM. It will usually do this until the car comes to a stop. Sometimes the idle will go down if I step on the clutch. The idle not coming down makes it difficult to use engine braking. This is strange situation and I don't know what could possibly be the connection between the clutch being depressed and the finally idle going down. This is also intermittent so it makes not sense to me. Wondering if anyone knows what engine control inputs would affect the IAC. BTW, I have replaced the IAC and the TPS, checked for vacuum leaks, replaced the PVC elbow and none of this made no change in the idle not coming down. Any thoughts?
