Adjust idle on Mitsubishi diamante
My car is a 1997 Mitsubishi Galant, and when it was idle it used to do the same thing, I was told it might be time to change the TPS Sensor (Throttle Position Sensor). I still need to change it, but what I figured out, is that when you let the car fully warm up, when the needle is as close to the middle as possible, it won't shake and turn off.
I believe on the 94 model it was the screw on the fuel injector right by the butterfly, if that helps... It's been awhile since i worked on theat car.
on the throttle body, side closest to fire wall, below where the throttle cable connects to the body, is a screw it has a 8mm jam nut on it loosen the nut, run the screw in to your preferred idle, tighten nut and done
maybe the valve timing is a little bit out
It could be misfiring. It could be set to idle too low. The timing could be off. Check what your RPMs are when the car is idling- it should be 8,000.
according to my pressure gauge on a 99 gst at idle about 50 and 3200 about 75psi
A failing throttle position sensor will cause idling problems when the car is warm. The failing sensor can also cause the car to stall when idling.
have lost my idle on a 1995 mitsubishi--what is the problem
Check the idle, crankshaft and camshaft sensors.
Check the motor mounts.
you cant adjust your idle, it is computer controlled
