I posted a while back. I got the service engine soon light! So, I take my car to the mechaninc. It was a p1404 Auxillary emissions control. My mech. said it was a bad egr valve. He looked at the car for me. I replaced my egr valve a couple of days ago took it to autozone. They cleared the light and bam a little while later the light came back again! How do I know if my egr is working? What is wrong!!?? I took it to the dealer, they wanted 49.00 to check it out and tell me what the problem is, they said if I get it fixed there they don't charge me the 49.00. I don't want to have to spend a ridiculous amount of money. Can anyone tell me whats wrong? Could it be my catalytic converter? or my 02 sensor? or my knock sensor?
