Vibration During soft acceleration
Hello-
I recently purchased a 1993 F-150 Lightning with the 5.8 351. When I accelerate softly it seems to start a vibration in the drive somewhere at about 32, 42, 55, and beyond 60 mph. If I give it the gas I don't have a problem. It does not sound like engine pinging, I have tried Fuel Injection Cleaner and Higher Octane fuel. Any ideas on what it may be. I have a center console and it too vibrates due to this other vibration. Let me know what you think!
Thanks,
John
