I could never move the throttle shaft up and down enough to cause any idle change. It did have a bit of play but felt like every other one at Pull A Part. When it did change the idle, it was when I had gone past pushing and pulling and began turning it. I sprayed some starting fluid on the shaft as well and it never did anything to really take note of.

Now, this evening's discovery of the vapor canister is exceptional. Driveability is smooth and seamless. I knew something was up when the computer kept the idle high on a long test drive. I turned it off and restarted it. It now starts immediately and idles smoothly at the right rpm. It no longer burns my eyes or permeates my clothes when I stand behind it. The exhaust has a healthy ring to it. Damn, I actually look forward to driving it tomorrow!

Don't just check the vapor canister lines. Check the can too!

Thanks all. Now I can think about shocks and the bald spots on the roof!
