what would make a 1991 f150 5.0 start vibrating and lose acceleration power
I was driving in a 35 mile an hour zone
and accelerated to 45 miles an hour
when the Truck started to vibrate and
acceleration power was sluggish
When was the last time you did a tuneup and filter change?
Last month I had the oil changed and a new air filter installed the truck was running fine then out of nowhere it started vibrating when accelerating and didn't have the power it had just the day before
