I'm not sure if its an electrical problem or not my tachometer will bounce up and down and the car will hesitate as this is happening, sometimes the tachometer doesn't even work and the car runs smooth. So far the mechanic has changed the cam sensor, the crank sensor, and the abs computer which he thought was shorting out the system, he also changed another computer I'm not sure what that was however the car is still not running right.

The Malfunction Indicator Lamp (MIL) is ON

This condition may also be the result of an incorrect installation of an aftermarket electronic device such as a remote starter or alarm system
