Vibration while the vehicle is moving can be isolated to suspension (tires, brakes, shocks, control arms, tie rods, etc).

Vibration while the vehicle is running but not moving can be attributed to drive train (engine for the most part if the vehicle is idling and not in gear) problems.

Being the methodical aircraft mechanic that I am, I grabbed a multi-meter, contact cleaner, and wiring diagrams. I cleaned connectors, ohmed out wires and sensors, checked for power and grounds. Everything checked good. By now, it’s showing ASD, crank sensor, and primary ignition codes. Then, with my wife trying to start it, I wiggled the connectors on the PCM. Every time I wiggled the gray C3 connector just right it would run. When I let go, it would die. So I took the connectors apart and tightened up the crimps (I don’t recommend doing this without the proper extractors and crimper). Threw it back together and BAM! Same problem. Well, time to bite the bullet and check for bad solder joints on the PCM board. I took the cover off of the PCM and realized that looking through the potting compound is like looking through Guinness Stout. But, I put it back in and hooked it up. It started stronger than ever, and didn’t even think about stalling. Yes! I figured that I finally got the connectors sorted out, so I left it over night to cool down. Got up the next morning and it started right up and wouldn’t stall even when wiggling the connectors. So I put the cover back on, put the PCM back in, hooked up the connectors, and BAM! It wouldn’t start! That was the point when my wife asked, “How’s it going?” And I, being the methodical aircraft mechanic that I am, said, “what the ----?” That’s when my wife turned around and went back into the house. While smoking a pack of cigarettes, I thought, “Gee, it runs with the cover off, but not with it on.” DUH, wonder what it could be? So I backed out the two screws that hold the cover on and BAM! It started right up. Then, while it was running, I tightened the outboard screw and sure enough, it died. Yes! Aircraft mechanics love it when they can make things stop working. I installed new screws (1/4” long, factory screws are 1/2” long Torx head), and she’s been running great ever since.
Now, will this fix a

It may be something as simple as getting your tires rebalanced. It happened to me and thats all it was :)

if the car isnt moving it could definitely be the MOTOR MOUNTS!
