put new plugs in now car wont start
i just put in some new plugs and the car wouldn't start. i finally got it to and it smoked like a ****. then left it running for a while, the smoke died out a little but it's still smoking a bit and the engine doesn't run smoothly. i double checked on the connections and everything. when i changed the plugs i took one out, then replaced it w a new one of the exact same # and then put the wire on, then went to the next. thanks for any help!

The coil pack that is nearest to the windsheild is the trailing coil pack.
As far as the leads, the front coil in that rear coil pack, goes to the front rotor top spark plug, and the rear coil from the rear coil pack goes to the rear rotors top sparkplug.
As far as the leading coil pack (the one next to the battery), the leads go to the bottom spark plugs. You can mix up front and rear on the leading coil pack, and it will still work.

I don't remember the color they are, but they're not interchangable. It's important that each of the trailing wire go to the correct trailing plug. The leading wires are interchangable though, iirc.

thanks for all the help. yeah.. i did do them one at a time.. but then all that smoke came out. let me get this straight... when you replace the spark plugs you just take one out, then put the new one in... like if you were taking out a bolt and putting in a new one, correct? i'm not sure if there are any special tricks to it becuase it's a rotary. lol i feel stupid asking these questions cuz it seems so simple but i'm just being extra cautious cuz it's my daily driver and i'm a poor college kid and don't really have money for a new engine... lol. thanks!!

they said that so you don't pull off all the wires and let them lay there like spaghetti and plug them into the first one you see. it's a trick for piston engines as well, remove a wire and spark plug, install new spark plug then reinstall wire all one at a time so you do not get them switched up.
if you did this then your wiring is not the problem but it doesn't hurt to double check and be sure the wires are in their correct places.

did you get anything at all into the plug holes while they were out?
they will smoke when flooded but it usually clears up fairly quickly.
white plumey smoke=bad
light blue smoke= burning oil, may be a problem, may not, depends on persistence
darkgrey-brown smoke=unburnt fuel and caused by flooding, normal when flooded.

Anti Seize should always be used when installing sparkplugs in an aluminum mount (such as a rotary engines houseings, or a import piston engine cyl head.
And it would not get even near the apex seals... well unless you slathered the end of the plug with it.

I never used anti-seize on components (such as spark plugs) that electrically ground through their threads. Never had any plugs seize up on me either, I guess I just know what kind of torque to put on 'em, instead of just "good 'n tight". That's not the type of application that anti-seize is made for, the base paste is not conductive in most formulas...Clean, dry metal-to-metal contact is essential for conductivity (the weaker your contact is, the weaker the spark's going to be, basic electricity 101).
Anti-seize was formulated for things like thermocouples, exhaust system hardware, or other close-tolerance hardware that must put up with extreme temps. Spark plugs are not close tolerance threads, that's why you can finger tighten them just about all the way down, if the threads are clean...

That is why you will see a little dab of Anti-seize compound installed at the factory on every Bosch O2 sensor made. Mind that a O2 sensor must have good conductive contact to work at all.

That could be the reason for the misunderstanding, then. The stuff we use on the aircraft (and I have in my garage- don't know how that got there, lol) is nickel (really high-temp) and copper/zinc (medium temp) based stuff, meant for the high temps of jet engine combustion. Never looked into any other stuff at the auto parts store.
Now the O2 sensor, I agree- with the temps we're looking at there, it HAS to have some safe anti-seize on it. But the plugs, they're right in the middle of the coolant stream through the rotor housings, so they can't get THAT hot...Let's just say I prefer not to use the stuff for my plugs, due to the fact I've never had a problem with them even getting close to seizing. What is it, 10 to 13 ft lbs of torque, or something like that. That's not much at all, so if yours are seizing, they were probably overtorqued (and no amount of anti-seize is going to correct for screwed-up/stripped aluminum housing threads)

But again remember a tiny pencil eraser sized tab is more than enough.
