Couple of issues with the 8 and need some help.

Hey everyone,

My car recently acted up and I can't pinpoint the problem and was hoping to see if yall can point out some tips/suggestions.

Mods:
BHR coils
Spark plugs recently changed out before this issue
Midpipe

Vid:

It started with me downshifting and going WOT. Right as I stepped on the gas pedal my exhaust note went from loud and changing to a quiet muffled exhaust note. I totally lost all acceleration and while I am traveling around 60mph in 4th...it sounds like I am driving 20mph in 6th gear. Its as if someone stuck something down my exhaust and clogged something up.

So when I came to a light my car would barely idle and completely stall. I have to rev it to keep it from dying and the rpms barely respond to my gas pedal.

When I got to my place I noticed that the exhaust was backfiring heavily when I revved it. It smelled heavily rich. I took the MAF sensor out and it didn't look too dirty. I have had issues with my MAF sensor (CEL) before, usually after some rain but couldn't find anything wrong with the current one.

I then pulled apart the spark plugs and found that the last spark plug that connects to the last coil near the driver is completely soaked with gas. All of the other spark plugs are dry except the last coil it was connected to.

I took off my BHR coils and put on some OEM coils and it still gave me the hard idle and a soaked spark plug. I tested each BHR coil and wires and each gave me no issue starting the car.

I am going to perform a compression test sometime soon. Hopefully a member can direct me with some pointers and tips to look into.

Thanks,
Dennis
