The Check Engine Light may illuminate with fault code P0171 and/or P0174 stored, indicating a lean fuel mixture. Our technicians tell us the left valve cover gasket, upper intake gaskets, vacuum line, and bolts may need to be replaced with updated parts to correct this concern.

    Code P0171 and P0174. Cyl 1 and 4 lean. Check engine light comes on and will stay off 24-36 hours when I turn it off. Is this caused by vacuum leak somewhere?

    I had the p0171 code so I replaced the pcv valve I removed the check engine light. Now I have recieved the p0174 light? I hear a hiss like a leak but cant fine it. I sprayed carburator cleaner to see if the idle changes but didnt notice any change. Also there is some kind of hesitation on take off? What can it be?

    I had this same problem. Seemed like a power drop and the engine light would come on. My mechanic said the is a know FORD problem with the intake and there actually a Intake manifold kit to fix the problem. Of coarse Ford will not step up and fix the problem. The repair Cost $800 but has run great ever since. Another poor Ford design.

    Check engine light, lean codes. Purchased intake gasket kit from Advance Auto Parts. Had purchase new intake isolator bolts online, as ford has changed the design. Also replaced spark plugs and wires, as its easier to reach the plugs on the back side with the intake off. Replaced upper radiator hose because had to disconnect from lower air intake. Total cost of parts was approximately $230.00.

    CEL on with P0171 and P0174 codes, have not yet done isolator bolt TSB 03-16-1 fix. Replaced fuel filter, air filter and cleaned MAF sensor. Modified LH vavle cover baffle to match new design, put inline filter in PCV line to stop oil migration to intake manifold, made sure U tube was clean and clear. Still getting codes, I am about to do the TSB fix.
