Q: Truck stalls

asked by on

My truck stalls when I stop.

The idle air control valve on your car may be defective, causing the low idle. A couple checks would have to be done to determine if this is the case: your engine needs to be checked for any vacuum leaks, then the idle air control valve should be checked for carbon sticking, and the throttle body should be checked. If all of these are okay, then the valve should be checked to confirm that it is within specifications, electrically. I recommend having a mechanic, such as one from YourMechanic, run a diagnostic on your stalling issue.
