Help: Replaced Coils...rich enough to dump gas out the tailpipe

So I just replaced my coils at 39,500 miles, and after letting my 8 warm up completely through several fan cycles, I slowly reved the engine to make sure it was all smooth, and it started studdering and gasping at 5k, couldn't rev above 7k, and after I let the revs drop and got out of my car (still on), there is small gas puddles under the end of each tailpipe.

So, running insanely rich, anyone think of what I did wrong? plug wires are still connected firmly, coils seated firmly. I just moved my stock airbox out of the way, didn't disconnect any sensors.

Yeah, just took it for a drive around the block, it won't rev over 7k, studdering and choking above 4.5k, CEL on, battery light on, TCS light on (I did not disconnect the battery, was told it wasn't nessessary)

I turned off my 8, waited a sec, and started it, it fired up after a long crank, and immediately died, same a 2nd time, a 3rd I gave it gas and it was choking but held revs until the idle smoothed out enough. Running super rich I assume, worried about it getting flooded.

Something wrong with the new coils maybe? Don't have a method to pull the codes, and leaving it running at autozone isn't appealing Assuming that it is a misfire code anyway.

Gonna check all the connections again, make sure the plugs wires didn't come off the plugs.

Nevermind. I'm retarded. I went to take everything apart again to put my original coils back in, and when I got to the part to disconnect the MAF(?) sensor from the intake, I found that it was still disconnected from before.

Reconnected it and everything runs smooth.

False alarm /facepalm.
