Subject:      O2 Sensor - situation 90' 2.1 (kinda long)
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Ok, so my 90' is alive and that is good. However, it is also still running a bit rough. I wanted to run this idea by everyone and see what you think.

It currently has a very less than stock exhaust. This was something created by the PO. It is quiet but there is no cat converter and no place to put an O2 sensor. I'm guessing the lack of an O2 sensor is contributing to my poor running. (runs fine at start up but starts running rich and loss of engine power after it warms up. Turn the key off and on to reset the ECU and it runs fine again for a couple of minutes - this cycle repeats).

Here is my question. I am planning on having someone drill a hole and weld a nut onto the existing exhaust pipe (where the cat usually is) and then thread an O2 sensor into the hole. I know that the sensor normally resides in the cat on a 2.1 but I figured this might work. Can anyone give me an reasons I just shouldn't bother trying this at all? Eventually I will go back to a stock exhaust - I just don't have the coin for that at the moment.

Question number two. Is there really a big difference in the O2 sensors that are ready to plug in and the others that have to be spliced? According to something I read the the pre-wired sensors are far superior. Your thoughts please.

Thanks ahead of time.
