Did you know there'* a vacuum line going to the charcoal canister in the front left corner of the engine bay, and did you check it as well?

If the rough idle smoothed out and things seem to be good. I'd check the line JDB mentions and off to inspection.

Started it up this morning, it stumbled a couple times, but did not stall. I did't have time to let it warm up all the way, but I think it is definitely good enough to go. Will drop it off tonight.

JDB - Yes, I actually replaced the rubber couplers to the charcoal canister, they were a bit baked after 12 years! I want to inspect the EGR pipe again. 950RPm still seems like a high idle to me. My Cosworth idles at 750RPM (dual DCOE webers) and my Corvette idles at 600 to 650 RPM.

Cold..our programming is in that area. Add onto that a little inaccuracy of the gauge and it sounds right in theory.

Your idle should drop down a bit once you warm up. It still won't hurt to check out everything for vacuum leaks though. Getting all that done will take a load off.

When I found the one cracked vacuum connector, I replaced all of them. They are all going to be in the same state of deterioration and it costs next to nothing to do so. Sure 'nuff, I found that another one was ready to go. When done, you shouldn't have to worry about that particular issue anymore.
