Yeah I've tried the tape thing but it still bugs the hell out of me. Plus I'd like to know if something pops up besides the o2 sensor that I should know about. I rent out my truck sometimes to tourists and it's not exactly the best incentive when you hand them a truck with the CEL on lol. What type of damages can I expect to see?

 

You also may run into issues with doing this - o2 sensors run on very tight voltage tolerances. If the connection isn't that great when you splice the wires, it will be useless and not solve the issue. Also the wiring colors are usually different, and it may be hard to find the correct splice pattern.

Also you would need to make sure the universal has the same number of wires (2 or 3 wires i believe for a heated sensor).

 

Well honestly, its hard to say. If things aren't perfect, as you know, problems can tend to cascade throughout the system. I mean its not going to explode or anything, but it could cause other issues, of which running overly lean could cause overheating problems which if severe enough could damage the engine, or running rich could eventually cause the CAT to clog for real.

 

Are we really trying to bring up backpressure again?

I know that was discussed in a thread and the myth was "busted" by someone...



Its not backpressure, its velocity that is the concern. And the cat has nothing to do with velocity.

 

Well i learned something today...

 

And this is why I hang here all the time.

I always thought that it was backpressure that was the concern.

Then someone smarter in that dept posted what they knew, and I learned a bit more.

I'm glad we've got users like you, dukie, who aren't d-bags about stuff. I like how you didn't get hard headed (like I often do) and get defensive over what I posted.

You, sir, are awesome!

 

I aim to please

 

Awesomeness should be implied until proven otherwise.

 

This is totally false, you do NOT burn more fuel without a cat, I am running a 93 4.0 with out a cat, in my CJ7 with 35in tires, 4.56 gears, my HWY milege is 16-18

 

The cat is emissions related NOT fuel,

I am so sick of people replying to a post that don't know what the hell they are talking about and are just to lazy to do a little bit of research on.

Look up catalytic converter and you see what a cat does

 

The deal is that its technically illegal to remove a cat from a vehicle that had one from the factory.

Because of this we are unable to discuss the true facts about cats and their removal.

So plenty of myths get generated by those who just make **** up that they think sounds good.

Keep in mind you are talking on a forum primarily visited by highschool KIDS and immature morons. Sometimes its tough to sift through the garbage to get to the good stuff, but its here. Somewhere.

 

I think it was pretty clear being that 80% of the conversation was about O2 sensors that thats what he meant.

And by the way, I'm neither a high school kid and pretty sure I'm not a moron. Truth be told, I'm rather offended by that comment.

 

I'm sorry you were offended by the truth.

I said primarily visited by, not completely run/used by.

Big difference.

Never did I say you were either, but assuming things may qualify you as such.

 

Haha, you couldn't get dukie to argue with you and you aren't going to suck me in either.

 

Hi flow cats can set an erroneous code for cat failure. A down stream simulator cures that issue. An even better option is if you can get access to a tuner is to have the code removed from the ECM.
