I switched the plugs and it moved to Cyl.2.

I'm guessing I need a new module?

A bad coolant temp sensor can cause misfires

already switched a little while back.

I'm pretty sure this is the upgrade from the black to the green one right?

FIXED!!!

for those who care, it ended up being a bad lower ignition control module. Got a new part and it fixed it up perfectly. As for the coolant warning, it ended up being a plug on the bottom that broke. Reconnected the wires and its all running great....for now. Thanks to all for the input.

These modules also require heatsink compound, very much like you would use on a CPU. If you have a vehicle with these modules, I would suggest especially if they are still functioning, to remove them from your airbox and giving them a fresh application of heatsink compound.

You obviously want to have the compound on hand prior to breaking free the bolts on the ignition modules even if you are just swapping them for troubleshooting.
