help with dodge spirit 2.5 egr valve or other problem?

I have a 93 dodge spirit with about 180,000 miles. It's been a great car. I'm trying to keep it going. The check engine light came on about 4 weeks ago, and the code came up for an EGR valve (32 code) and now a MAP sensor or vacuum line (13 code). Now it's not just the light being on that's the problem. Now the engine runs really fast when in park at idle, and it gets really hot (not overheating, but i can feel the heat around the intake manifold and the temp gauge runs on the upper end of normal). ( I did pull the existing valve, and with a blunt metal pin punch, I was able to push the valve in the EGR in and out, so the valve seems to open and close. It did have some loose carbon that fell out when i tapped it on the ground.) I'm going to try to swap the EGR and see if that solves all these problems. Where would i find the MAP sensor on the engine? Could all these symptoms come from a Bad EGR valve? Please copy responses to my email at snipped-for-privacy@hotmail.com

They are excellent utilitarian cars. I've owned several.

Vacuum leak. Probably in the MAP sensor line.

Put in a new EGR valve. Your EGR crossover tube is also probably thoroughly clogged by this point.

The MAP sensor is on a black rectangular bracket secured to the firewall, directly forward of the windshield washer tank filler. It has a rubber vacuum line connected to it, about 5" long, which at the other end connects to a hard black plastic line. The whole vacuum line must be intact and not cracked, broken, clogged, melted or otherwise damaged.

While you are under the hood, now's a great time to put in a new Oxygen sensor (Mopar, NTK, Standard-BlueStreak or ACDelco, not Bosch) and you're probably overdue for a complete crankcase ventillation service and throttle body hose inspection, with a change (since you've got nearly 200k miles) to the large-bore PCV valve.
