obdII code p1385 trouble

ok so im cruisin the highway today, and all of a sudden out of no where, the temp gauge bounces all the way to over heating, and right back down to normal temperature, and then everything went down hill. engine light start blinking like crazy, motor started bucking, so i hopped off the next exit. sitting at the stop light on the way to my local tech school, who i am close with the automotive teacher there, the truck is hoppin all over the place missfiring, cant idle, having a hard time running. at this point i came to the conclusion i hate my blazer. so i made it to the tech school eventually and had it scanned with a really really nice snap on diagnostic tool. 3 codes popped up, 1st maf voltage low (didnt worry me to much, my maf has been fried since it sank last year, 1 motor ago). 2nd, random missfire. 3rd code, p1385.... i couldnt remember what the code said, but it had something to do with the pcm, knock sensor, and abs system. i called a dealership, and he told me the abs and the cat. are prime culprits of this. funny thing is i unpluged my abs last week cause it was pissin me off not lettin me stop in the snow. and my cat is all sorts of messed up, the element is broken inside it and i can hear it bouncing around and rattleing, and i think its blocking off my exhaust pipe causing a high pitched whistle when ever it gets into high rpm's. so anyone have any expereince with this, or solutions, besides getting that jeep i wanted to get my hands on latley?

anybody ever heard of this??? anyone...

Not in my data.

so anyone have any expereince with this, or solutions...?

Since you know the MAF has problems, the ABS is unplugged, and the cat is falling apart, I'd start by repairing those.

well i did the abs and the cat. i changed the maf but it still says theres a problem with it, not sure if i got a faulty maf or not.. was fine on my buddys s10. so all those have been fixed, still having the problem, but now only random missfire at idle.
