I am thinking it might be the coilpack. how would I check to see if the fuel inj. is spraying? I would think it is not bad because it runs fine after the engine warms up.

Does the misfire only occur when the engine is cold?
If so I think you are back to a temp sensor.
If it is reading a warm engine you will have no choke on a cold start, it will not want any throttle untill it actually warms up.

yeah it will only misfire for about 2 mins after I start the car up. and after that it runs great. I hav also noticed that it is not everytime on start up. I would say that 98% of the time it misfires but here and there it starts up fine.
