Hello my car runs very well except for the ac but that is a different problem. I recently smogged the vehicle and it easily passed the emissions test, but failed the EGR functional check. EGR visual says ok. The valve is original, but new one is quite expensive(240.00). Any sugestions to pass this check? Can replacing the tubing and plastic valve do it or do i need the EGR valve itself?
Thanks in advance
Bret
