Black smoke from engine compartment
If someone could help me out that'd be great, here's the story... I was driving my car (87 non turbo) and the heater core hose blew out, I drove 2 miles home, got a new hose and figured while I was in there I would change the spark plugs and put in a k&n. When I started the car it thumped like a lumpy cammed v8, I figured it was misfiring so I pulled the plugs and they were all fine. I drove the car a block, no power, real choppy... I got the car back to the house checked some stuff, tried to start the car again...HERE'S WHERE IT GETS INTERESTING... when I went to start the car BLACK SMOKE started coming out of the engine compartent somewhere near the exhaust manifold. Anyone have any ideas?

So I went outside this morning to move the car into the garage, and it started, fine... so I drove it a little bit and it was like nothing ever happened, the black smoke was gone, some coolant burnt off the block from the heatercore hose but besides that it's like nothing ever happened? I couldnt get my hands on a compression tester today, so that will have to wait. Would the black smoke have come from excess fuel still? maybe it was flooded? I'm royally confused. One day she's dead, the next she's fine.

maybe you dumped something (oil) on your manifold? Black smoke is more usually associated with burning oil. I'd still check compression, just to be sure. There's also the possibility that something was just shorted out from all the coolant, and that's why your car ran like poop before.

I checked compression, 100 in front, 105 in rear. I started her up and she ran fine... I know I'm new to rotories, but honestly... should it do that? lol

as for the original problem, put the plug wires back in their correct spots, don't listen to these goons.

And the OMP is the Oil Metering Pump.
If one of your lines or cracked, or it's leaking... it's right near the manifold on the front of the engine.

Make sure your VAF (airflow meter) is plugged all the way in. Might have jogged it loose when you installed that K&N, and if you do the ECU will do all sorts of crazy things!

running w/o coolant is almost guaranteed to crack a coolant seal. keep an eye out for overheating and lost coolant/overflow tank filling up.
as for the black smoke.. do you ever smell gasoline in your car at all? if you do its bad and im sure someone here will love to explain it to you.
but hopefully its just some oil.
