Low rpm misfire/stall

Out of nowhere I went to take off from a stoplight today and it stumbled & cut out like crazy. Once I got the rpm's up it ran fine. Next stoplight it stalled when I came to a stop. Just replaced the plugs 800 miles ago. The ignition coils show no sign of arcing. I just washed it and thought maybe something got wet, or maybe bad gas since I had just filled it. At idle it runs like it's missing. Any ideas on what could cause this? Could a coil just go out completely? It is an 03 and i am aware of the coil problems, but the insulator's are fine. I have a set on order from the dealer anyway. This could totally ruin the weekend seeing how I'm suposed to be taken out this cute little hottie tonight.....

Recall on the denso ignition coils on all 2003 R6's. Go to your local yamaha dealer and get them replaced for free with the newer mitsubishi coils. I think its technical bulletin 2003-016 or something like that.

Edit: D'oh! Didnt read your post fully, get the coils changed anyway
same problem im in too... i've been reading up and going to do a TPS cleaning. i suggest the same to you.
