Car idleing low and dying when it gets hot

[Gary Hanson Jr]

My 1995 Mitsubishi galant es has not been running in a few months because of my own personal injury (dislocated knee) and now she’s acting funny. When I first start up my car she’s running at around 1200-1500 then as the car heats up the idle gets lower and lower. When it’s hot it idles around 100-300 rpms and just cuts out. So I’ve cleaned the Mass air control sensor (with the specific spray for it), cleaned the throttle body and sprayed into the IAC real good too. Still bad. I’m thinking its time for a new radiator since it comes out tan/brown but I just replaced the temp control valve about 6-8 months ago. Would I need to change that along with the radiator?

Any help would be great and very helpful. If I put this post in the wrong area or did something wrong I’m sorry. I’m new to the forum and just need help. Thanks alot… Stay dirty!!!

when the car idles at its lowest try tapping on the IAC
with the handle of a screw driver.if the idle changes replace
the IAC. also if the car has ac turn it on and see if the idle
comes up. if not replace the IAC.

Also you might check for air in the cooling system. This video should help you with that.

In addition I’d also check for vacuum leaks. BTW you can also use water instead of carburetor cleaner.
