This is GTIKID, i'm logged on from my friends computer though

so today (friday 9/16/05) i'm at the track and i get in a few good runs since it was fairly empty...they were my first runs at a track and i did so so...my best time was a 15.8. But thats not the point. On my 5th and final pull, i'm racing my friends GSR. I launch good, 2nd gear goes good, 3rd gear NOPE! I actually shifted into back into 1st gear! Some of you might know what happens when you do that. Anyways, i freak out and get scared as shit. On my way home though, my car was doing fine for about 10-15 minutes and then all of a sudden my CEL starts flashing and i'm like uh oh shit and my car starts sputtering. I pull over, restart my car and the CEL goes away. Another 5 minutes down the road it turns back on and begins to sputter worst! I pull over, turn the car off for another couple of minutes, start it again and the CEL is still there. I finally make it home, unplug the battery, hook it back up, CEL goes away, and the car is still sputtering. HELP! What could be? i read on the vortex that it could be a coilpack and i'm hoping thats what it is. I'm gonna get it scanned sunday b/c obviously tomorrow is NOPI, but if any of you guys might know what it is or have a clue, please let me know. Thanks!
