Hi Rich. You're right, my #'s are hard to read.
Basically I failed the HC both at idle and at 2500rpm.
The max at idle allowed is 120, mine was 431.
The max at 2500 allowed is 140, mine was 261.

My catalytic conv. is not oe, it was replaced 2 years and about 30k miles ago. I was kind of suspecting that myself, but I'm still not sure where my engine fault code (EGR) is coming from.

Thanks for any ideas.
Jeff
