Question about 2002 Cadillac Deville
Well the dealer should take care of it for free if it is the same problem. Call them and take it back.

Try unplugging vacuum line from the EGR valve and plug the hose with a 1/4 inch bolt.

SOURCE: MAP sensor 1994 Cadillac Deville
The map sensor shouldn't cost more than 50 bucks or so. It is very easy to change, and can be done w/ simple tools. It mounts to the intake manifold. There is a wire connector that plugs into it. Just remove the two mounting bolts, and the connector, and it will pop right off. This is not a tough repair, so it can be done in about 10 minutes at most. This should save a trip to the repair shop!

You would be better off going to a Cadillac Dealership and paying the diagnostic fee. Spend $65 to find out what the real problem is rather than replacing parts until the car runs properly. This way you get it from a Cadillac Technician. Once you know what the problem is you can decide on where you want to have it service. Because you are paying for the diagnostics you shouldn't feel obligated to have it done at a Dealership. Please leave me good feedback if you feel this has helped.

Anytime I get a too lean DTC I first change the fuel filter if it hasn't been changed in awhile. You'd be surprised how many times this has helped.
Good Luck with it.
