just a thought, but if you were in under there tinkering with all that stuff, check over everything, vac lines, wires, connectors... make sure nothings got broke or cracked...
i had a problem on mine a while back where it ran like crud, and it turned out i had shut the hood and a piece of removed wire loom plastic stuff scrunched down on a vac line connection... it cracked the 20+ yr old dried out n hardened hose, on the underside where i couldnt see it... found it by accident realy, then broke another piece trying to fix it...
anyways, point is, id double check over everything and make sure its all hooked up n nothing partialy loose or something after tinkerin...
and on mine, i know the easiest thing to do is just let it idle, and pull the vac hose of the distrib and stick my toungue to it, (or a vac gauge if you got)
