What year car?, Which model/engine and what tranny?. If your check engine light is on, your cars trying to tell you whats wrong with it.

2000 cav 2.2l manual tranny

If the light came on there is a code stored. i would have it checked and go from there.

Vibration could come from wheels being out of balance.

the code was P0440A I know it's EVAP and i know that's its not the fuel cap what else could it be

for the shaking it could be wheel bearings, for the studdering my 02 2.2L does the same thing but im not too worried bout it but i would check the the plugs, wires, air filter, and gas filter.
