Car will start fine but will not hold idle once warmed up. Dies after running for about 10 minutes. Computer reads barometric pressure sensor code. I bought a new IAC and map sensor in hopes that would work but I cannot seem to find map sensor. Could you give me an exact location for the map sensor in a 1993 Dodge Stealth SOHC base model? Thank you in advance for the help.

The barometric pressure sensor is in the MAF itself. I have tried to change it with no effect. I have also replaced the fuel pressure regulator, all 6 injectors, plugs and wires, distributor cap, and ignition coil. I believe the IAC is fairly new, but bought another replacement that I will put in this week. I bought the MAP sensor from advanced auto. It has 3 prongs for a plug and a port for a vacuum hose. I have the service manuals for 93 stealth and cannot find any mention of a MAP sensor. The part is year and model specific, but is it possible the car does not have one?
