    P0401 Again....Dammit!!!!

    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!!!

      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.........
