Need major help. 4.2 98 auto
Having a problem that i can't solve. At beginning my truck used to shake only in park. Then slowly started shaking in drive only in lower rpms. Now seems like it shake all the time in drive. Less when just at a light but more in lower rpms. Have replaced plugs, wires, coils, and engine mounts. Cleaned iacv and maf. Took it to a mechanic he couldn't figure it out also. He said there was no misfires while accelerating but was misfires when decelerating. No check engine light. Another thing. When accelerating I can hear like a little jingle noise and when I put my foot down at higher rpms it sounds like bbs in a tin can. Thanks. Any help would be great.

Going back to when it would shake only in park. What did it do when in neutral? Did it still shake? What's it do in neutral now?
Do don't mention the year of the truck but have you looked up the service bulletins from Ford?

Wow. I'm sorry but he clearly has an issue that a little mystery oil isn't going to be able to solve.
