Why would a 96 Cavalier 2.2 sputter and stall intermittently with a gas fouled cylinder 2 plug?

You changed plugs and wires and the problem is still there? Well assuming you did that already, My 91 cavalier did the same thing. It turend out to be the electronic ignition control module on the back of the motor. 20 bucks from a junk yard. Mine went a 240,000 miles. I just answerd how to change that to another person on here.
