OK I have cleaned the EGR line. It was totally blocked. The Shiner Bock is in the cooler.

Good suggestion on the mixture but I cannot control the mixture since the O2 sensor and the associated control system will bring it back to normal. Unless I force the mechanical adjustment so far out so the Lambda control system cannot correct it.

So I am headed to get the car re-checked. If it still fails I guess I will go for the cat next. But if jbaj007 is correct I should pass now.

Thanks guys for all the wisdom.

Have a good weekend. I will let you know on Monday what happened.
