2004 Ford F-150 FX4 5.4L MIL Lamp on
Posted to Ford Driveability on 5/11/2011 9 Replies

Our problem is low power, dieseling, and 3 Mil P0012, P0340, and P0345. Phasers check out OK After clearing codes, truck runs fine for 5 miles, then bogs with MIL lighting up. Then low power. Does run with VCT unpluged, but low power.
