Ditto that. And also, when you get a chance, I'd love to see a new thread from you with pics on your trans swap. I would use it and link to it to update my list of Honda trans specs and swap possibilities: http://ecomodder.com/forum/showthrea...tml#post378478. Right now, that list follows the advice of a trans specialist who claimed the 4th gen trans could not be swapped onto 1992-2000 engines. But it sounds like you did it without trouble. That would be a useful thread too.

Anyway, good luck!

I have a few pictures from my swap. Not a lot. A few pictures of my tranny open up too.

It still threw a code 48. But the used cat sounds clogged too. Not sure if that causes it to throw a code 48

There has got be something wrong with the sensor itself, the wiring, harness, or connections. That's specifically a heated sensor 0 2 Code. A clogged cat would be bad too, but if the code has appeared and you can't clear, I have to think the sensor itself or its connections is the top suspect. Have you investigated the pinout?

[nitebluesky]

The mechanic guy check it out last week and could not find anything wrong with the wiring or pin out. I might have to fess up and buy another expensive 02 that I can't return if I open the package.

I'm going to hallow out the cat maybe. I put my header back on and put it on the original spot where it worked the first time. Just in case the 02 may work. The gasket for the cat has a small leak too.

You should be able to put a flashlight under the honeycomb and see through it. I vote use the hf exhaust and clean out the converter if you have to. I can send you an o2 that I have laying around that didn't throw a code. It had a bad stumble but it will give you the answer you need without guessing on a brand new sensor.

I've purchased a new 02 sensor today. This one has a red wire oppsed to blue wire. Not sure if there is a resistance difference. Ill eventually install the 02. I think I burned out my other 02 in less than 3000 miles. Thanks for the offer slownugly. My car had been averaging 28mpgs. With those numbers I should have thrown a gsr motor in it.

Well the new 02 sensor with the new exhaust, cat and downpipe still threw a code 48. I heard the oem one has 7 wires as opposed to five wires. So tomorrow I'm going to look at an OEM sensor.
