Check the coil packs. If they are not bolted down they may be loose and not touching the tops of spark plugs. That is the only thing I could think of moving from a bump up. You know black smoke is unburnt gas, so check everything that gives it spark. Could be loose ignighter or wiring. I hit a turtle on I-10 going to jacksonvile once, shut dented the frame rail!

Sounds like either you have a bad leak or a bad maf....did you pressurize your FMIC/vacuum system to make sure nothing got disconnected? Visually checking it doesnt always mean you'll spot the leaks.

Looks like a big crack and crushed in the FMIC is the problem! Damn alligator!

I just saw my FMIC was crushed and had a crack. once I replace for a new one I should know for sure.

alrite for one the black smoke coming out of your exhaust is oil... 2 the tickin noise could be anything from lifters to a bad rod... as much as i hate to say it you should probably take off your valve cover and make sure all your springs are tightened on correctly and if its not that then i'd go with bad rings... just not sure as to how the damn alligator fucked that up

If his FMIC is fucked, my $5 says he fucking dented his oil pan too and pushed it against the sump. Now the engine is dying from oil starvation....

but bro he already said he replaced his FMIC because that was cracked and whatnot and checked the oil pan which was fine, i mean doesn't help to double check i suppose but i''m still going with what i said

Well yes Oil pan looked good, but you know this car the oil pick up is milliliter from the pan. so who knows. also I checked plugs and the all DONE maybe running rich fouled my plugs and made the car misfire and witchcraft then happen...

Or this might be a new problem all together.

alirght so take the pan off and take a look... also you're saying your plugs are done? do you have any oil or burn markings in the cylinders where your plugs are?

i know its a little late but dont you think fragments from the broken intercooler traveled into the engine. i crushed my intercooler and by the time i got home i saw a piece of metal just past the throttle body
