So lately my 93 KA24de has been having a weird idle issue.

I read that the IAC Valve could be the culprit so I took that off, took it apart, cleaned it all and reinstalled it.

Well before I started the car, I decided to check the MAF sensor, but like a dumbass I tried unscrewing the screws holding the black plug to the top of the metal MAF piping. I didn't know the MAF unplugged from the back of that piece. I proceeded to pull that the MAF wire plugs into out. My friend also used some electrical contact cleaner, but he sprayed it into the MAF unit.So now that car will start and want to immediately die, but if I rev it, it will idle wildly from 800 to 1000, to 2000. If I accelarate, it won't go past 3000 RPMs and it just bogs back down.
Also, black smoke is pouring from the exhaust, and the smell of gas is in the air.

Did I royally f*** up the MAF sensor? My research says yes, i just want a confirmation. At any rate I've already ordered a new MAF sensor, got lucky and found one on eBay for 50 bucks.
