MISFIRE ON CYLINDER 1 - WHY?

2000 Chevrolet Prizm • 419,800 miles

I replaced all 4 spark plugs w/iridium plugs. I also replaced all 4 ignition coils on Friday 3/30/2012. The engine light came back on on Sunday morning. After I did all the above, why would the engine light come back on and show a misfire on cylinder l? I would like to donate at least $3. I don't have a credit card. All I have is a debit card.

Have you checked to see if your loosing spark. Or inj pulse. Test this or if you need more help let me know. Also is it running poor?
