Engine Performance problem
1999 Ford F150 V8 Two Wheel Drive Automatic 158000 miles
I changed the spark plugs I put motocraft plug in it.
But my truck is still shaking are you could say jumping when I push the trootle in it only does it when I go up a hill or get over 40 mph. I had a computer check my service engine light it said the number 4 cylinder was misfireing could it be the coil pak.
