Average Mileage: 100,527 mi (46,000 mi - 146,000 mi)

Verified

On higher mileage vehicles, one or more EGR orifice in the intake manifold may plug with sludge. This can cause the engine to misfire when first accelerating because too much exhaust gas is directed into the cylinders where the orifice is not plugged. Cleaning the clogged passages should correct this concern.

    My Freestar has been sputtering off and on when I try to accelerate, sometimes stalling out on me. It can go days without doing it, then do it all day long for a few days. So far, we have tried changing the fuel filter, and other things my husband thought it may be. We will be checking the EGR Orifice, seeing if it is plugged up.

    Mis-fires - We get error codes that say cylinder 1 and 3 are misfiring (P0301 and P0303) We also just got code P0352-Ign coil B primary Secondary CKTR - Have not researched that yet.
