If check engine light is on, you should bring it to your nearest Autozone and have the error codes read. You may have a dirty Mass Air Flow sensor, throttle body, or EGR valve that could be causing your issues. Or having a bad O2 sensor will make your car run poorly. If you get the codes read, post them back here and someone will look up the meanings.
