New timing belt New idle air control motor. Cleaned and adjusted fast idle air control valve ( thermo valve on d-side). Cleaned t-body. Have base idle set to 700 -+50rpms. Timing set to emissions sticker. New distributor, coil, wires, and plugs. Have used carb cleaner try to find a vacuum leak and no change in idle. No codes found. Check and purged all air pockets in cooling system using air bleed screw and a bottle over radiator filler neck to raise coolant level. One weird thing if I plug the hose coming off the air boost valve on the far end of the intake from the t-body the idle will start to surge from 800 - 1500. Not sure why it does that. The stalling problem is worse when the ac is on. Any help is welcome. Thank you.
have the same problem?
