I have a 2005 dodge neon and shakes when im at a red light stopped.

you probably replaced the upper and lower mount but did you replace the middle mount that is in the frame rail?

is the engine running rough or is there only a vibration?

I got all 4 engine mounts new and it runs great it just the vibration wen im stopped at a light or just warming up the car

thats weird, it honestly shouldnt then. i know you might have a little extra vibration with the a/c on but not much.

Yes it is mayb ill have the motor mounts checked again

has it only been like this since its been very cold out?

I got the same problem with my car 2005 dodge neon 2.0 I put a new motor mount all three wires spurs n coil clean the vale intake with Seaford dome n liqueur n it still vibration when you put it in drive.
