Missfire at idle only....Opti??

Hey guys, still trying to figure out whats up with my car. I hooked up a scanner to it and it showed missfire on #6 and #3 cylinders only at idle. The car has stock opti and plug wires (60k miles). Car runs great untill you come to a stop and it starts missfiring at idle and will stall while the cars in drive, no missfires at WOT. Plug wires show no sign of being burnt. Could it be the dreaded opti?? Help guys, this is getting pretty damn fustrating.

Thanks

Take a look underneath at night and see if you see any arcing from the wires. Look at your plugs and measure your wires and rule that out before you take your water pump out to check out your opti. You might also want to check out your throttle position sensor and MAF sensor.
