Howdy folks.
I had code 1404 come up on my car today so I pulled the EGR and to look it over. It looks nearly new with hardly any carbon build up on it. The plunger moves free without any resistance at all. ( I realize it may still be bad ) After some research I came across this http://engine-codes.com/p1404_pontiac.html Can someone elaborate a little more about the reprogramming the PCM. I assume this has to be done at a shop? Or dealership ? Ive been searching the multitude of threads on codes but cant seem to find an answer for this particular problem. I forgot to mention Ive only had my car for 2 weeks so Im still learning about it and unfortunately I do not have any records of previous maintenance or issues its had, if any. The car runs great but I would like to nip this in the butt before it gets worse.
