Code 332
This code translates to EGR valve opening not detected. If you have vacume to the EGR at the wrong time it would open the valve and you would have a rough idle at idle speed. If you have vacume at the valve when your suppose to and the valve doesn't open, then you might have a bad EGR valve. The way to test this is to put a vacume pump (hand unit) to the vacume port on the EGR and see if the valve opens. If it doesn't the diaphram in the unit is damaged. Some times you can see the EGR shaft within the ERG move when applying the vacume. If you can't see the shaft. Start the motor and connect your vacume pump and see if you can create vacume. If you can the valve will open and you'll have a rough idle. Release the vacume and the motor will return to normal. Also one other thing, These EGR's are prone to carboning up in the passage ways. I have seen this cause a code. Hope this helps, Dave

I thought 332 was thermactor system inoperative right side. This is NOT the egr system. My '92 had this code from the day I got it, but it never affected mileage or performance.
The place to start is on the drivers side valve cover behind the ignition coil. There are three solenoids there. The round one is the EGR solenoid, the two square ones are the bypass valves for the A.I.R. (thermactor) system.

It sounds like the egr position sensor is going bad. If you use a non dealer part here it gets dicey, a lot of times the shaft (the pin that the EGR moves in the sensor) is either too long, or too short. This causes this code. You might try a new sensor, but stay away from the cheapo box parts stores for this one. I'd use a napa, carquest or dealer part only.
I might have been thinking of the 331 code... It's been a few years since I owned that van, several since I drove it.
