This just started happening a week ago. I'm going 65 and all of a sudden my engine starts shaking as if its having trouble accelerating. i'm able to accelerate faster but as im going faster, my car starts shaking even more .. i dont know why this is happening. i swapped out my engine for a brand new one exactly a year ago. does anyone know why this is happening?? HHHEEELLPPP PLLLEEAAASSSEE!!!

 

not to point out the obvious, but HOW IN GOD'S GOOD NAME CAN PEOPLE HELP YOU WIHTOUT MORE INFORMATION! when you ask a question is is best asked in such a way that you also provide information. such as: what year, type of motor, transmission, etc...

 

what regular maintenance have you preformed on the engine since it was dropped in

 

sure it is your motor and not your susp.....shaking like bitch.....

 

mine did that at around 55, but it was due to my horribly unbalanced tires...but after speeding up it was better.

i would look into doing an alignment and balance/rotate tires, and suspension, before you start looking into the engine.

 

Definitly check out the suspension alignment and the tires. It happend to me before and it turned out to be a worn out rear tire.

vibration at highway speeds is an unbalanced tire problem, def get em rebalanced and youll be all set. if not, then it could be ball joints.
