'99 Sunfire Engine Shakes

I just had a engine rebuilt in a "99 Sunfire with 2.4L. Now the engine shakes like craze. I had the engine mounts replaced when the rebuilt engine was put back in, so I know its not them. Please help!

Could be caused by a couple things. Low grade/quality fuel with cause detonation which will cause knock. a ignition issue or clogged injectors could also cause it to shake. Good Luck,

is it like shaking like.... rough idle shaking or is it like when you give it gas it kinda jumps back? if its a rought idle it could be your gas, it could also be a clogged fuel filter, or dirty injectors, anything in your fuel system really, and if it is not, i would check your mounts

Does is make a whistle or whinning sound at all? There is alot of possibilites.

this is easy for me mine did this 2 or 3 times before. replace ur coils and coil cover. one time it was the coils. then i had to replace the coils again. then it done it again i had to replace the coil housing which is your coil cover. try this let me know if it works. good luck cause mine wont crank. sunfire isnt a good car I come to find out the hard way.
