If your idle was fine and then just became high, don't adjust the idle control screw. Your problem would be indicative of another issue. Perhaps a vacuum leak. turn the idle control screw to the left ... no neither of those.....your are getting air that is accounted for by the mass air flow sensor....there for its either a) throttle plate not closing or b) idle air controller stuck open.
To fix high idle problem on a 1996 VS Commodore, first locate the idle air control valve. Unscrew and unplug electrical connector running to the valve. Turn the valve over and clean the sensor for debris.
tps throttle position sensor
No problem, bring it in first thing in the morning and i will get right on it......
Before you can fix the idle problem on your Vauxhall Frontera, you need to find out the cause of the problem. If the problem is with the fuel pump or fuel filter, they would need to be replaced.
The idle is automatic. If the speed is not corect then you have to fix the problem with the idle motor.
May be idle position sensor.
U need to clean the throttle body and also clean the idle air control vavle
buy a can-am and it will fix the problem
Correct the idle by adjusting the idle screw on the throttle body if all else fails replace the idle control module located upper center of firewall usually. Hope this helps
manually under the hood.
Because something is broken, or your idle speed has been set WAY to high. Try to fix this soon.
Tune up.
