Needing Some O2 Simulators

I don't have emission test here in Arkansas. I am not worried about having them on there or not. When I unplug them it seems to run better. What would be the best "coating" for the headers. Also it has the bosch O2's that were put on there about 7000 miles ago. I have not had a problem out of them until now. I just really don't know which way to approach this. I hate having to deal with these problems.
How are the O2's supposed to look? I took both of them out and they "looked" fine. I didn't remove the spark plugs. We were pretty careful around the plugs but you are right about maybe damaging them. How can you check them for being cracked or damaged? I took them out and they appeared to be fine.
It's all about a ton of things I sure you know. Some places, like in arizona in the summer, you may not have issues with bare LT's, but more likely than not, you'll at least get the codes on one bank. I had mine on the passenger (B2) side only. Driver side was fine. But I agree...OEM o2's, hotter o2's for the front and see how it goes.
just kidding, he's top notch, he'll be able to help you.

I am not saying your truck is odd, just that this isn't an unknown problem. I would never put my money on a 4L60E lasting on a FI setup (especially with TM removed) but there are guys with them still ticking. Doesn't mean it's a good idea, just that they are still working for some. There's always going to be a handul of people that get away with stuff like this (like yourself). Every setup and situation is different. I am no expert, but you see this as a common complaint enough to say there is a good chance it will happen if you put long tubes on. Your combo works for you. I spent a stupid amount of time researching my problem, no matter what I did it wouldn't go away. So I turned the damn codes off...eventually stayed open loop. Good for you man. I'd be very surprised if the poster's prob is anything but what I described. Unless he actually damaged the wires to the sensors or both sensors by pure bad luck are defective. (you should troubleshoot those right away no matter what anyway)

I am going to try the o2 idea. I really hope this is it. If not oh well. I prob need new ones anyway. Now which should I go with. NTK or Bosch. Any recommendations?
