Recently the check engine light has been staying on. At the last oil change (68K miles), the mechanic tested the engine and thinks it could be the E.G.R valve but I have to spend $60 to find out what it is exactly. How much can I expect to pay to fix the E.G.R. valve? Can Autozone tell me what it is so I can just pay for the repair? The car does not stall out so he seemed to think it's a "minor" repair. Funny, I think Toyota should replace the "check engine" light with a "$$$" symbol - it would be more appropriate.
Thanks.
