I have a 2000 f150, 4.6l v8. I have two symptoms that I think are related but I am not sure. The truck has 92000 miles on it. No trouble codes.
1st. I get a vibration at about 67 mph that seems to pulsate.
2nd. I get a similar vibration at about 1200 rpm in park. This one seems to be much worse when i lift my foot from the accelerator.
I have had-the truck about a month, and just had the tires rotated and balanced.
Any help would be appreciated.
