My galant shakes pretty hard when i put it in drive, in neutral or park it doesnt do it as bad but its still there.

There is a clicking coming from the engine and i dont know if its a piston or if ive got a stuck or broken rocker arm.

Any help would be appreciated
Thanks

check your engine mounts, and if its a light ticking coming from the engine it could be your lifters. Its a common problem with all DSM's
