and i thought i smeltsomething funny but then i got out and smelled again and it really wasnt anything.
but i rarely go past 80 and i just stayed on till 100. so im thinking some throttle thing? or timing?

Pull codes, if you smelled something, check under hood for burnt wires.
If it runs fine while revving the engine, most likely it is a sensor or a leaking injector(s).

I gun mine multiple times each & everytime I drive it
If it can't handle WOT often,I will find a car that will.So far,corvettes & the 98 z28(ls1) that I've owned take it no problem & enjoy it

Well the. Real answer is that you have an older car that has never been pushed; or at least on a regular basis. So you either 1) moved some gunk around messing with your iac or sensor or 2) ran it rich (engine load over 90% is not limited to 14.7 afr) which coated sensors or slightly fouled ur plugs.
Here's my list.
-Spark plugs ($3-4 Bosch ) replace as u were probably due
- iac remove and clean or spray brake/Carb cleaner in the idle circuit in the Tbilisi
- fouled o2 sensor let the ecm give it lean conditions to knock the carbon off
- check for vacuum leaks
- the smell was probably excess fuel, is the vacuum lines to the fpr okay?cracks?
Like most people have said, a 100 mph isn't much...so it is more likely that the car needs to be driven!

When I first got my C4 it had trouble starting and would idle really rough (and almost die sometimes) the previous owner never really drove the car and it sat most of its life. I replaced the fuel filter, PCV valve, cleaned my throttlebody, and ran a bottle of Techron through a tank of gas. The car starts fine and idles great after that.
