93 dakota 3.9 auto backfire, bucks and misses when cold.
Started by pulling plugs, antifreeze ran out cyl3. Pulled intake, gaskets were stock but not leaking, plenum gasket leaking slightly. Pulled passengers head, definite gasket blown. Haven't fully cleaned the head yet but don't see any cracks or evidence if them. All bolts broke free with the exception of 1 driver's side exhaust flange bolt, that side of the flange twisted off instead of the bolt lol. Easy fix just gonna need a split flange.
EDIT: Scrolled up, got my answer.
Here's the spec sheets out of the 1993 FSM; I'd again recommend you obtain one. Worst case is about $40 from Bishko directly; used on eBay for paper or new from Summit Racing if you just don't want to order directly from Bishko.

Thanks, but mine is a 3.9 v6. Will have to go to storage and pick up my books. Pretty sure I have a Chilton for the correct years just gotta remember which box lol. Gasket set was supposed to be in yesterday at 2, still hasn't came in.
