If you have 97-99, replace your ICM on top of the airbox. It controls firing/firing order. It's notorious for failure and causing cyl 2 misfires, etc. Don't drive the car like this though. A misfire is one thing, but driving around on 3 cyl's while cyl 2 gets flooded with fuel is bad bad bad for your cat.

On top of the airbox. If the coil pack on cyl 2 works on a different cylinder, it's definintely the ICM, just get a new one. They arent too cheap though. Autozone/advance offer one that is Hucco brand which has been proven reliable for around $100.
