Still have not found the cause of this. I have not worked on it much since March, but am thinking about getting back to it now.

I made an EGR block off plate and installed it where the EGR pipe connects to the intake just to see what happens. Did not change a thing. The car still idles at 1500 warm with a misfire. Runs great above 2000 rpm.

The fact that the EGR block off plate made no difference, does that rule out an EGR issue?

Here's the latest from the OBDII scanner:
Codes
P301 misfire cylinder 1
P306 misfire cylinder 6

System monitors not meeting operating conditions:
EGR
Catalyst

Any fresh ideas?
