Power Loss - 01 WS6 The car is a 2001 WS6 M6 w/37k miles.
The problem:
Feels like it loses about half it's power but still runs. If I push the clutch in and let the RPM fall back to idle and kick the throttle a couple times it usually gets back to normal, so far this has only happened when the car is warm. This happens once or twice a day depending on how much I drive. It will also just completely die as I'm slowing to a stop, but this happens rarey (ish), about once a week maybe. Also have noticed that on occasion when I start the car it will start briefly, pop (backfire, but not loud), and die. Start again and runs fine; this happens every few days or so.
The check engine light is on, but only throwing a code for an inefficient cat on bank one. I'm going to take it to the dealer to get those replaced (warranty) as I'm not going to change out the y-pipe/headers for awhile.
Any information to help me troubleshoot this problem would be fantastic.
Posted this in GenIII Internal Engine...guess that was the wrong place.
Thanks,
Colin
Did a hard pull on the way home from work (it was running great, or so I thought), looked at the rear view mirror and white/gray smoke was gushing out the exhaust...uh oh.

Forgot to mention if I go full WOT there's a lot of popping out of the exhaust (not loud, more like crackling I guess...rich/lean?). I don't go WOT for that reason, I'm trying to troubleshoot and fix as I go. Guess it's time to go buy a new battery for the ZX6R so I can rest the Bird for awhile, lol.

*****...called the dealership and they said the warranty is only 6yrs/80,000 miles on the cats.......And let's say I'm NOT willing to pay the price they're asking just to put stockers back in.
What do you guys do with an ORY as in what do you do about the O2's that read for the precats? I have to be able to pass emissions (scan only), but I'd like to eliminate the precats.

You have an 2001 F-Body. That year car had a specific recall on the cats due to premature failure. I'm not sure what the bulletin number is-But I had to do it for my car a year and a half after owning it. It would not rev much past 5k, and you could hear popping in my exhaust at idle. This was a slight miss due to a clog in my passenger cat. Find the bulletin and take it back to the stealership.

Well, I left a message with the service department this morning. Hopefully I'll be hearing from them soon about this. And I'm hoping to hear it's still under warranty...otherwise I'm not going to be able to do anything about it for awhile.
Anyway, question still stands though...how to do true duals while still passing emissions. Hell, I'll have a couple cat shells put over the pipes so it looks like I have cats. But what about the O2s?

As far as the visual inspection, if you're concerned take the old cats and knock out all the guts and weld the empty cans back on. Put the rear O2s in the pipes after the cats and tie the wires up so they look conected to something.

I'd just make sure to hide the rear O2's really well. Where I'm at they're pretty lax about the visual, just hold the mirror under the car and barely look.
Now it's just a matter of finding someone in town that can tune out the AIR and rear O2's......

Not to over hash this thing...but the issues my car is having could all be caused by a clogged/clogging cat? I'm going to call the dealership again and see if I can get anywhere with them, I'd rather just replace the cats for now and not have to worry about the forced upgrade yet...

I actually just got back from picking up my car. The dealership did it under the warranty, otherwise wouldn't have done it obviously. Had to fight them the entire way though, had to MAKE the service person look up the dang special bulletin.
We'll see how the car runs now, but I'm highly sceptical that the cat was the cause of the random power loss the car has.

Just a suggetion. If the car is still acting up try cleaning the MAF and replacing the O2 sensors if they have never been replaced. I changed all of those plus the fuel filter when when my car was still mostly stock and it made a world of difference. Stupid K&N oil spray will kill the MAF

I'll take a look at replacing the O2 sensors, thanks for the tip.
Already cleaned the MAF 2x in the two months or so...I believe it's ok. And replaced the fuel filter about 2 months ago.
Been thinking about dumping the K&N and put a normal paper filter in because of all the negative posts about the K&N filters.
