I have 06 GT Automatic. 185k miles. Been having a Misfire for a bit now,can’t solve it. Replaced Coil and Plugs. But it seems to be breaking my plug electrodes very quickly. Just put a new(er) plug in 2 weeks ago and the electode was blown off.

I take that as a clue,but a clue in which direction idk. Rough idle and choppy acceleration for the misfires. All I can think of is fuel injectors,wires or... I ran w low coolant for about a month. Maybe warped my cylinders?
