What causes an engine to hesitate when accelerating?
What causes an engine to hesitate when accelerating? Probable Causes: An engine that hesitates, stumbles or misfires when accelerating or when it is under load, is an engine that is either sucking too much air, not getting enough fuel, or misfiring. Why is my Chevy Cruze skipping during acceleration? This may be a good thing anyway - it makes the fan run-on in hot weather to prevent coking in the turbo. I should also point out this happened under heavy load as well. 1/2 throttle or more. Keep in mind 1/2 throttle on an electronic throttle car may be 75%...
