1994 Plymouth Acclaim - 3.0L 6 cylinder - 128K

This car seems to be working fine, but every once in
awhile the "Check Engine" light comes on. When I check the
codes by turning the key back and forth a few times, I get
12, 32, and 55.

12- batttery has been disconnected
32- EGR?
55- end of codes

Since the "Check Engine" light doesn't come on constantly,
I figured maybe it was some kind of false message. So I
disconnected the battery terminals for awhile to clear the
codes.

It took awhile, but eventually the check engine light came back
on, and I got the same codes; 12, 32, and 55.

But the "Check Engine" light still does not come on every time
I drive the car. When it does come on, it's usually after I've
drive the car for at least 10 minutes.

Any suggestions appreciated.

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.
