The "check engine" light will "light" when there is a malfunction in the engine management system. The fault code is then stored in the computer. The computer must be scanned to retrieve these stored faults to pinpoint the malfunctioning component. We recommend buying your own scanner and doing it yourself. With a pocket scanner you can check for fault codes to find out why the light came on in the first place. You can clear your cars trouble codes after you replace the malfunctioning sensors.

Hello! when you say you checked the MAP sensor what do you mean? Did you take voltage readings at idle ? A vacuum leak is the likely culprit, especially to the MAP...The minor shake at idle being the major clue...Send a comment...guru..saailer
