Suddenly, out of left field, I reappear.
Life got hectic, and the poor GTP got parked for the better part of a year and a half.
Been driving it around some, replacing normal wear and tear parts, and getting it ready to go back to the dyno.
Went to fire her up yesterday, and it really struggled to catch, and when it did it started to pour smoke out the exhaust. I shut it down immediately and started tearing into it.
Found this gem.

Cleaned all the coolant out, pulled the plugs, disconnected the fuel pump relay, and turned it over. Spun over fine, ejected the coolant, and sounded fine. Got a new core that should be here tomorrow, along with everything to do an oil change and plugs.
