I always had this code 32 problem. I posted a topic here a couple of years ago but no one had any idea of what could be wrong.Always when i started the car if the engine was cold the ecm sended a code 32 and the engine always hesitated a little. So now i removed the plenum( 2 years after the problem first showed) to polish it when i found the problem. Some previous owner had crushed the cable running from the egr to the ecm underneath the distributor. I dont know how he did this but after replacing the old cable everything works again.

 

Im having the same code and was wondering what cable are you talking? or do you meen vacume line? thanks
