Occasionally the "check engine" light comes on in my mom's 94 voyager with a 3.3 L engine. Usually after driving approx 40 miles and restarting upon her return trip. It doesn't seem to affect the running of the vehicle and the light is usually off the next day. AutoZone checked it and pulled up a code 32.

Apparently it references the EGR transducer solenoid / circuit. I'm not really too experienced with mopars, so any help is greatly appreciated. Anyone have any diagnostic procedures they can share?

One other thing I noticed...... When driving the car and giving it full throttle the AC vents seem to deflect to the defrost instead of the dash vents. This kind of tells me there may be a vacuum leak. Do the brake boosters ever go bad? How about the brake booster check valve? is there a vacuum storage cannister?

Could this be tied in with the code 32?

Thanks,
Karl
