I've replaced my EGR valve w/a new one from work. I know Autozone doesn't always have the best quality of parts, but then again, who does nowadays?? Have any of you ever had issues w/the Wells brand EGR valves? What the hell else could it be??? I'm getting sick of this dumbass problem. Iv'e never had this much trouble w/any particular code on any other particular car except this one and it's getting really old, really fast. HELP PLEASE!!!

have you cleaned the EGR port from the EGR to the UIM?

I just tried that earlier today. I got a piece of coat hanger all the way through to the other side of the plenum opening where the TB is. Hopefully, this fixes it.........

It did the trick for me

Well, so far so good. No code!!! I hope it stays away.......for good!!
