For ** PETE ** : ) I looked at my controller valve, here's what I did... 850 1995

My apologies, let me correct my last post. The yellow hose does not go to the IACV along with the white hose on my car. It goes directly into the surge tank (air intake manifold) right next to the idle air control valve, right under a slightly large hose. No hoses go directly to the EGR valve from the EGR controller on my car. Strange.

Also, I put the vacuum gauge on the controller at the yellow hose port, and got nothing.

You know, I have neglected to tell you that along with the 2-4-1 code I am getting I am also getting a Lambda 2-3-2 code. I think this means mixture too weak. Someone a while back told me that if I take care of the EGR, the lambda should take care of itself. Does this sound right to you? I value your opinion and am sincerely in your debt for the assistence.

Kevin
