Lately the truck has been a big sluggish in the morning and down right ornery on damp rainy mornings. Under load and part throttle it would miss going up hills , the fuel mileage had fallen off a bit too

So with 119,600 on the clock I did the 120K service this afternoon . Besides Oil and filter, I replaced the plug wires and fuel filter ( all Motorcraft) I cleaned the MAF , installed new PVC Valve and grommet. I changed the transmission (manual) fluid .

I also replaced the Autolite plugs I put in at 100K with Motorcraft, Autolites are suppose to be the same plug but the truck has been a bit off ever since I put in the Autolites .

That is a happy truck now!
