i looked at the spark plug and the one on top in the back was burnt to hell... im gonna be trying to figure it out tomorrow.. anyone have any ideas?

seventhgear

well first do a complete tune-up(wires/plugs/oil/fuel filter) the whole nine even the coolant if you want. [[[ ALSO:buy ngk plugs and wires ]]]
then you check for probs.
TPS MAYBE OUTTA WHACK if problem maintains after tune-up
if there is still a prob after the tps which i doubt there will be then post up
hope that was helpful.

also these rotaries go thru plugs like they are goin outta style so maybe every 4-6 months they should be changed unless rode on hard then change them maybe every 2-4 months

well... now that i think about it.... you know when you first start and it revs high for the first few seconds... well it starts to rev up and down like there might be a tps sencer .... would the tps sencer make the car run like that then when i go back to try to start it... it wouldnt start... let me know

Do what seventhgear said, new plugs and wires is always a good thing.

The TPS sensor /can/ make it rev up and down like that. (it did with my 86 GXL) it's easy to adjust and there's a few writeups on how to do it online.

If it doesnt start it might be flooded.

well we did a few tests on the car... its getting spark and its getting fuel... so we went and bought a compression tester... and its getting 80 psi on the front rotor... and the needle doesnt even budge on the back rotor... its got to be the apex seal.
