So my car shakes pretty good at idle. It doesnt do it right away but once it starts it keeps going. It shakes my exhaust pretty bad which causes vibrations and rattling noise(exhaust is not loose at all) that are really loud. The shaking followed by the vibration and rattling is worse when the air conditioner is on and when the engine cooling fan kicks on. I checked all the motor mounts and the front one was bad and I replaced it but it didnt change anything. Also changed an engine ground cable that was supposed to be grounded to the chassis that had snapped and that also didnt change anything. I checked the spark plugs and Coil on plugs and everything is good there. There are no check engine lights or no history of any codes. Please help.
