hey im getting terrible gas milage (10-13) with my 2002 xlt with the 3.0. i changed plugs, wires, fuel filer, oil, and ran injector cleaner. i was inspecting my air filter and took my air outlet tube from the air intake hose and relized someone taped it all up. took the tape off and noticed that the engine ran alittle smoother when i put my thumb over the tube instead of letting it suck in air. i was wondering if there should be a pcv or one way valve somewhere on that hose? its killing me!
if thats not the case, anyone have any other ideas to bring my gas milage up to where its supposed to be?
