Engine Mechanical problem
1990 GMC Truck 4 cyl Two Wheel Drive Automatic 101160 miles
I have a postal llv vechile can the idle air control valve cause a vechile to excellerate after taking out of park to a high rate of engine speed and show no code and braking still keep a high rate of excelleration with the brake on and only stop excelleration when you turn engine key off but when restarting engine seems to idle fine day temp roughly 70-80 degrees would it make sense to change the idac valve for safety
have the same problem?
