Default O2 Extension Fried

I have been recently experiencing horrible "hiccups" in my 99 WS-6 at low RPMS. I took it in to have the computer check it out and it came up on the program that the O2 sensor was "insufficient". The guy told me your O2 sensor is either fried or not working properly. So i took it home, put it on the jack, and looked underneath. My O2 sensor seemed to be fine but the 24" O2 extension had had it's protective covering melted off. The O2 extension runs RIGHT next to my LT Pacesetters. At one point it was touching, it's not now b\c what was touching has melted away and now the wires are exposed with less than an inch of space between them and the headers. I know i'm going to have to replace my O2 extension but i wanted to double check that it's the O2 extension that is causing these problems. I mean, the wires were exposed but seemed to be completely intact. Could the heat be interferring (sp?) with the electrical junk? I dunno. I was hoping you guys could help me out. Also, when i do get a new O2 extension, where the freak am i going to run it? I can't let it hang. I can't put it back where it was before b\c the same thing will happen again. Any ideas?

He also mentioned that since i installed LT's i'll need to upgrade my spark plugs and wires. Is this true? He said your stock ones can't handle the heat that aftermarket headers give off. If so, what will i need to get?

i'd go as far as saying anything can affect the o2 signal, including cutting and extending the wire, and everything else people do. I have some pieced together extensions on my car and whenever it rains my car runs a little shittier than normal, i know those extensions i made aren't water proof. But i'm gonna get some vette ones to fit right anyway. When you get new ones, try and tie them away from any heat source if it is possible, i forgot what that area looks like.

And i havent heard of it being a necessity to chnage plug wires when you get headers. But sometimes people run into problems where the wires actually touch the headers and they definitely cant take that heat.

Well the wires ARE touching the headers. Some at least. Those that aren't have maybe an inch of space between them.

Could i wrap my O2 extension in some sort of insulator? Something to shield it from the heat? Because i dunno where else i would put it.

I just ziptied my extensions out of the way, so they would not touch the headers.

mine are tucked around the opposite side of the oil filter, between the filter and the pan and they havent melted, i guess the pan isnt as hot as the headers. that might be a quick fix. which side is it because that'll only take care of the drivers side, my pass. side is already pretty tucked away so thats probably not your problem.
