1994 Acclaim - Code 32

Pull the EGR valve and clean the pintle and seat. Then check it by applying vacuum to the valve and seeing if it moves. Then make sure the passages are open. The 3.0 is known for burning oil which creates a lot of carbon. Also look at the vacuum control valve for the EGR.

I pulled the EGR and cleaned the pintle and seat with carburetor cleaner and q-tips. I do not have a way of creating a strong enough vacuum, so I couldn't do that part. I was able to push on the pintle with a toothpick and and make it move back-and-forth. When I removed the vacuum hose from the top of the EGR, at first I couldn't see an opening in the metal tube that the hose was connected to. After a little spraying and picking, I found a small pinhole. Is the opening supposed to be that small? It's a factory original MOPAR 4287780 EGR. There seemed to be liquid inside the EGR. I'm not sure if it was carburetor cleaner or water. By plunging on the the pintle, I was able to force all the liquid out. The liquid was rusty looking. All of the other passages seemed to be open. The openings on the engine where the EGR connects were lined slightly with carbon, but they were not blocked. I was unable to check the pipe that connects to the exhaust pipe. I reinstalled the EGR, and disconnected the battery for awhile to clear the codes. After driving the car about 6 or 7 short trips, it appeared that the 32 was not coming back, but after a 20 mile trip, the "Check Engine" light came on, and I confirmed the code 32. The odd thing is that the engine seems to be running fine with or without the code 32. There may be an occasional time when it stalls out after coasting into my driveway uphill, but generally speaking the engine runs great.
