Hello i have a 95 mustang 3.8 with 150k miles runs good but! it has a really bad shake randomly like as if i am going from a new road too a dirt road for a split second of i let off the gas for a sec or if i keep my foot on the gas it stays or if i full throttle it it takes like 3 seconds to go away but does it around turns too at 50+ mph can someone help!

 

Could be a lot of things, wheel bearings, u-joints, motor mounts, or transmission mounts. Or a whole lot of other things could be the problem, more info needed

 

well its hard to explain but its bad but i noticed that im doing about 50 and i am at 1100 rpms

 

Do you know anything about cars, can you jack it up and get underneath it and check the things I listed?

 

yes i know a lot about cars but i never worked on a mustang before and yes i will be getting under it tomorrow

 

Automatic or manual ?

 

Try simple things like tire pressure and rotation , balanced
