1993 LT1 RPM Hunt in Closed Loop I think I am nearing the end of chasing all the demons out of my LT1...I still have some issues however. Currently the car will RPM hunt between 500-950while it is in neutral AND moving. When the car is fully stopped the idle settles out fine. Does anyone have any ideas on this? Car is a 1993 Z28 M6
List of new parts (Many were from other issues I was having)
1. Replacement ECM from madtuner
2. New Engine Harness
3. Knock Sensor
4. 2x Delphi 4-wire o2 sensors with fastbird conversion harnesses
5. MAP Sensor
6. ECT Sensor
7. Relatively New TPS Sensor
8. EGR and AIR are gone and tuned out.
9. New Opti
10. AC Delco Platinum Tip Plugs
11. Plugs Wire are relatively new and in good condition
Is it possible that this could be VSS related? (I have no DTC's.)
Everything is well Grounded...Just to throw that out there first
