An intake manifold vacuum leak can develop from a variety of sources, often causing illumination of the Check Engine Light with codes P0171 & P0174 stored. Thorough diagnoses will be necessary to pinpoint the cause in order to make the correct repairs. A "smoke" machine is often used to isolate the cause of difficult to find vacuum leaks.

Check Engine light comes on and stays on. Does not flash, just stays steady lit.

Bought the car used, engine light comes on for loose gas gap. Bought new cap, no change. Bought tool to reset which I do about once a month.
