Whatcauses the engine to vibrate in gear

There are lots of words in here, but even after reading many times they don't make sense. I can usually tidy up text, but you beat me on this

"T Problem Starts After E Drive For A Five Minutes And T Char Barmas Sub. When I'm in gear and stand in (note driving) the four vibrates worm hard."

especially on the 'T Char Barmas Sub', and 'the four vibrates worm hard'.

Actually after reading it another 20 times, this is regarding an aftermarket amplifier system that the kids use to bust their eardrums and make themselves deaf in later life?

Your battery isn't man enough to run the sound system.

check the engine mounting for damages & transmission mounting.also check the mounting bolt for looseness and tight...

check engine mounts especially the rear box mount because under high torque situations (1-2) gears there may be mis-alignment of the drive shaft occurring and the vibration is from "U" joints behind the gear box getting out of alignment and phase angle.. Check slip joints for lubrication and wear.

have you checked the motor mounts? A bad motor mount will shake rattle and roll.

I would have to be tghere to run tests, this is a hands on type of problem.

Have you at all serviced the automatic gear box? one possibility is the gear box.Also the vibration is either broken gear box or engine mountings broken or weak.

Get a friend to open the hood and look at the engine go up or down in the engine compartment when the brakes are firmly applied and switching between reverse and drive. Look for the motor mounts for behavior where tears exist in the rubber.

Increased vibration from a vehicle indicates worn out engine supports. This vibration often disappears when revving the engine high, but is very noticeable at low revs.

You can have these inspected and possibly replaced to reduce the vibration cominf from your engine.

Hope this helps.

Does it run fine going down the road, Just vibrate at Idle or does it run bad too with a check engine light on?
