Misfiring #2 and losing coolant

I have a 99 ga gt 3.4 I keep getting misfires on cyl. #2 plus I am losing coolant. I need help. Thank you

How many miles are on it?
I only ever lost coolant on mine when my waterpump went bad which seems to happen at 85-90k miles

Just hit 95,000. I changed the water pump and thermostat a month ago. I am having the head gaskets compression tested on friday.

oh sorry to hear that.
Best of luck!
