I didn't notice any sparking, but of course the engine is still bogging and surging at idle... at one point it seemed as though it may have been running normally for a moment then back to jumping around - so perhaps it is just a plug wire that may have been pulled from its boot a little and is intermittent because of this? - if in a corvette it was merely missing one cylinder from no spark, would it cause the engine to get continually worse (does it flood that cylinder and could that be why I started smelling something at the end?).

"Also when you put the wires on it is good to put some di-electric grease in the boots.It allows it to go on easier and you can feel the clip going on easier as well as helps next time the need to come off." Redeasy
And don't forget to do what Redeasy said above. It could be a loose wire or one that's just barely making contact. You know that solid little click as the wire "cap" goes over the plug? That's what you need to "feel"; you won't hear it. This will be the cheapest fix, if that's what it is.

Well since all you did was change the plugs....what did you set the gap to? I would borrow a ST-45 spark tester and check each wire and the coil. The ST-45 looks like an odd spark plug, any mechanic should have one. This is the procedure from the service manual.

they were gapped to 50 as it said in the owners manual - when they were first driven with they smoothed out the engine tone a little but it performed perfectly before and was no different after the plug change or after a couple days and a highway drive - it wasn't an immediate problem - I'm going to go ahead and buy new wires and replace those and see what happens (They should be done anyway).
