AnyBody got a lighter? (fuel related)

Well this car must have a very wierd computer problem. I have the problem when i start the car the thing idles for a min then the idle jumps up and down, its stall then gets it self back up, so it goes form 200rpm to 2000rpm really quick, as if its stalling but saves itself. Well my main problem is i got have the car sit there for about 10mins and warm up till the temp guage starts moving or the car goes wacky.
Ex: Last Night i left my friedns house around 11 and when i backed out i noticed a car was comign so i floored it, it spun the wheels allot (was wet out), i go into second and i felt like i dropped my transmission and it stalled out, i cranked it and cranked it, until it finaly started then sounded like it running on two cylinderes and all i was smelling was gas. Anybody have a lighter? Well i let it sit there in the middle of the road(wouldnt move) and run(while traffic was moving around me) and i then limped it about 300 feet down the road, still missing really bad, then all of a sudden the thing was back to nromal, full of power and nothign wrong!, WTF! it does this allot!, and its really annoying! im runnin 94 octane gas and the timeing set at 12* , and it still does this. but i may have another problem, i noticed im only getting 15spi of boost, i bypassed the BCS , but the boost stops at 15 now. any ideas? this car is really wierd! i love this car more then anything (well nto as much as my g/f, had to put that incase she reads this!) but any ideas on the blasted dialy driver mutiple problems will help!!! and getting 12 mpg is really annoying when i paying 1.85 for a gallon of gas! all help is greatly apprecited!

Carlisle was fun!!! sorry id dint get ot meet every one. hopefully next year will be better with my car all painted and cleaned up!!! Thanks in advance!!

Like Pete said, pull the codes. I'm gonna bet you have an erratic iginiton code. I've had about the same problem with two of the TCs I have owned. They would run good for a few min. then go whacky, then be OK untill it cooled off again. Both were the cheap, made in china iginiton module.

For one it was the reason the previous owner got rid of the car. He was sick when I told him what I did to fix it. No, I didn't take advantage of the guy. Bought the car at a auction after he had traded it. Talked with him sometime later.
