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. If the Check Engine Light comes on, you may find any of the following codes: P0171, P0174 Lean fuel condition codes.
A bad hose in any part of the engine is easy to fix. Sometimes, vacuum lines cause a rough idle due to a vacuum leak, and these lines are also simple to replace. A common cause of an engine running rough is faulty ignition timing. Once the timing is adjusted, the car should run smoothly. The idle speed may also be set too low.
