Idle Issue

Asked by Aug 23, 2010 at 01:55 PM about the 1987 Toyota Supra 2 dr Hatchback

Question type: Maintenance & Repair

Recently started to have a Idle issue after engine comes to temp, at stoplights RPM's drop to 600 and car has definite miss and "popping sound" as tach bounces, I have done diagnostic on Dist, cap, rotor, wires, coil, connectors, O2 sensor, TPS, etc. The last thing I need to check I hope is the Idle speed control valve.
Any help would be appreciated, thanks.
