I have an 2002 Eclipse GS. When I first drive my car, even after warming it up and I stop at a light I can feel the engine shaking, a very noticeable shaking and I am pretty sure I can hear the exhaust pipe shaking as well. This persists until I get my car to above 40 mph and then the shaking stops for the rest of the day, until my car has sat for a while in which it does it all over again. It is not the engine or the transmission mounts because I just changed them. I just replaced the spark plugs and wires, pcv valve, even flushed the fuel injection system and I still have not figured out what the issue is. My check engine light has not come on or anything. Does anyone know what could be causing this issue?

Scan for codes, check fuel pressure with a gauge, auto parts rent it and check for a vacuum leak
