For a month I have been driving with the CEL on. The car drives fine. The only thing noticeable was that when the car is idling the front end of the car vibrates slightly.

I pulled one code. It is 1302 (MAP/Baro Switch Solenoid Valve). I checked all the hoses to and from the valve and they all looked fine. As a last resort I bought the solenoid valve. I changed it today. Then I went for a drive and the damn light came back on again.

If anybody has any suggestions, please give them.

Thanks
