Anybody with any ideas?? We are thinking it'* the Map sensor. Any suggestions, please feel free to give me your input!

Thanks!

P0108 EGR Barometric Pressure Sensor Input Signal is out of Self-Test Range.

P0121 In-Range Operating Throttle Position Sensor circuit failure.

Start by testing for vac leaks.

Will this cause anymore damage if we continue to drive the car short distances while we wait for someone to look at it?

Hard to say without knowing what the problem is. I would suggest not driving it. But if you must, drive as little as possible.

NEVER replace a part based only on the DTC definition. Each DTC has a set of testing procedures, instructions and flow charts that must be followed to confirm the location of the problem. This information is found in the vehicle'* service manual. Always refer to the vehicle'* service manual for detailed testing instructions.

I've seen hundreds of error codes that were nothing more then a vac leak. Generally when you have multiple codes that are different, it'* a leak. When checking for a vac leak, make sure you check the EGR tubes. They crack some times and get missed a lot. Spray carb cleaner on all the lines while the engine is running and listen for changes in RPM.

I just had both these codes on my 1998 Bonneville. Since I do not have the means to run the tests that the factory manual suggest, I went looking for vacuum leaks. Found my MAP sensor'* rubber seal was pushed down into the PCV housing and not on the MAP barb. I replaced the MAP that of course came with a new seal and it fixed it.

But I would do as suggested above, check for vacuum leaks around the throttle body (squirt with a carb cleaner while running, idle will rise if the carb cleaner momentarily fills a leak). Also take the PCV top off which the MAP is plugged into and make sure it is all sound. Also while you're at it change the PCV valve, only $2.50 and it is before the MAP and could cause anomolies.
