I have a 1996 Saturn SL1 automatic transmission. The SES light came o and I went to Autozone to get the code checked. Code is P0404 whic relates back to the EGR valve. I have tried to clean it once, althoug I'm not sure how well of a job I did. Two questions: 1) How much is an EGR valve for a 1996 Saturn SL1 automatic? 2) I have been told that the part is discontinued for my make and mode car. I was quoted 6 for a new EGR valve from AutoZone when I kno others have gotten the same part cheaper, MUCH cheaper. Can this thin really be cleaned well enough to pass inspection w/out forking out couple hundred dollars? Thanks! Ashle
