'91 exessive idle? -SOLVED
Update for anyone following my previos thread.
Throttle linkage not returning back to stop screw on trottle body-causing idle of 2000 rpm.Would knock back down with a blip of the throttle.
Installed my (fairly worn) original factory trottle body back on the car but with a new coolant passage plate and (another) new IAC valve-not delco this time though.
Car idles at just the right rpm now,and idles super smooth.
Just bought a scanner finaly,shoud have bought one of these things ages ago! All sensors/ecm etc running as they should but noticed my dash tacho is 500 rpm out to high! Is thair any way to re-calibrate the tacho? if not, would an aftermarket autometer tacho hook up to the dist alright?
My other analouge gauges are out aswell.The tach will drop 150rpm though when you shut the drivers door
