1- check for codes with scanner to see why check light coming on. 2 unbolt exhaust before caterlic convertor. Run car to see if still does it.If it does not the caterlic converter is the problem.the car temp should not go over 220 degrees. if car is getting to hot it will shut off,check cooling system and cooling fans to make sure they are comming on. Also if water is flowing through thermastat.Map sensor when gets hot could cut out. some places to look. doug

It is located at the back of the engine near the firewall.you will have to pull the engine forward to gain excess,Just disconnect the motor mount at the front of the engine and use some straps to bring it forward so that you will have room to reach it.I just replace the one i had on my 1990 olds cutlass supreme just last week.
