I have not noticed any abnormal driving experiences but I have noticed that my fuel mileage has not been the greatest. Is it possible that there is a leak (pulled code at Autozone. Error code P0456 indicates 4 different issues: loose fuel cap (car has no cap); EVAP canister broke, hose cracked, or not connected; Purge or vent solenoid defective; and the last and seeming to be most likely cause, Vacuum leak at engine. I do work at a Ford dealership but I was unable to get a mechanic to take a look at it today. I am extremely worried about it doing serious damage to my engine. Could this potentially cause a long term issue and also void the warranty to whatever it may damage?

Hi blainhershberger,

Installing or using any aftermarket product will not necessarily void your warranty. However, if the product fails or causes a Ford part to fail, the cost of the repair and any related damage(s) are not covered by your warranty. Let me know what your dealer says; if you need my assistance, just let me know.
