1996 Chevrolet Cavalier, 45,000 miles. After the engine reaches normal operating temperature the engine will suddenly quit (diesels) when coming to a stop. It does not do this until after driving for a while. I have accessed the trouble codes and got a code #23 (MAT sensor problem.) I got this code from a repair manual. The illustrations in the manual are vague and generalized for several models and makes of cars and I am unsure of the location of this sensor. I believe it is on the air cleaner housing. Could the problem be carburetor and fuel mixture related? Also, how do you set the timing for this make and model? (Yes, the mileage is correct if you are wondering.)

The MAT (manifold air temperature sensor) is located to the rear of the intake manifold slightly to the left. (Driver’s side) Your problem could be fuel mixture related. The MAT sensor may cause the problem. To set the timing, ground the diagnostic connector, and B terminals (upper right two terminals) set timing at 8 degrees BTDC. The diagnostic connector is located under the left side of the dash on the right of the fuse block.
