welp I’m back. there’s a total of 5 catalysts, I’m assuming the front 3 are “pre-cats” but they’re pretty roasted at the front of them, I can only see into the front of the passenger side catalyst. I beat out the chunks with an extension and got the front part of the honeycomb out but behind that it’s got plenty of melted parts clogging it up. Assuming the driver side is in the same condition and the fact that I can’t stick anything inside the pipe to beat out the rest of on the other 2 I’m just gonna get her the front 3 branch new. Her rear two are alright, nothing melted on them just some piece of what blew out the front 3 was on top of it. I’ll put the photos of the front 3 Y part and the rear 2 up. I need to figure out which part I need for the front? I found some numbers on the cats but nothings matching up on rockauto or anywhere I’ve looked. I need to get the right ones. Are the part numbers I need on the headers by chance?

Mine did the same thing a few times. But it always stumbled and sputtered on startup. I would just let it be for about 30-40 sec. and it would clear out. Now on high humidity and strait up rain days, it ran like crap and got worse with time. I replaced the ignition coil. All of those issues are gone.

The over 50 deal.... I found the speed limiter on mine, 92mph.
