Default Bosch Universal O2 sensor installed, no more CEL. (more)

I had a damaged Zoldman secondary O2 sensor, and with the recent price hike, I decided to take a chance on the Bosch universal the ECS and a bunch of other places sell (I got mine from partsamerica for $75).

It's basically an o2 sensor with no connector. You have to connect the 4 wires yourself to the 4 wires on the connector, after cutting your connector away from the old O2 sensor. The included directions make this easy.

It's been 80 miles, and the CEL light has not come on. I'll try to check for codes again today, to see if there is anything else in there.

I checked for codes after driving around 45 miles yesterday, and there were no new ones (I had a P 154, which was the original problem).

More to come after I plug in.

Bank 2, Sensor 1 no activity detected. Basically, I damaged my Zoldman when doing DPs.

Default MPG is unknown, since I just replaced it. I will monitor. Performance is fine. Better idle than

before.

I just gutted the precats last weekend, which caused the original damage to the O2 sensor.

I hope to get some Gtech runs in in the next couple of weeks to compare HP numbers. My last Gtech runs are in my sig, but that was before gutting the precats.

Default This is so old guys. I spliced an O2 sensor on my '93 S4 and never had a problem. I soldered the

wires together. I don't crimp stuff, that's cheap sh*t. What I'm saying is, don't be affraid to do it. If you work on your own car, I assume you know what you are doing so this is an easy job.

Default FWIW, I spoke to a technician who went to Bosch training where they told him that crimping was

preferred over soldering... something to do with the heat in the wires.

Not saying that I disagree with you or that I wouldn't solder mine, but just passing along what I was told.

I've heard something like that before too. I am completely against crimping, it's just nasty!

Default I agree. I did STFA for many hours, and there is quite a bit about "don't use universals."

I believe that they were talking about using non-Bosch universal sensors, though.

The connector module that comes with it seems pretty sturdy and functional. I used that.
