O2 sensor shot?

[flatsixjunky]

I have no evidence to back this up, but was always told that the solder will affect the millvoltage travling the wire. Is it true?? i dont know for sure but i have alway crimped mine and had no probs.

You can try soldering it, but the solder does not want to stick. And for applications that take a lot of vibrations, crimping is the way to go. Use quality crimps. I think the sensor wires are steel or something. I ran into the same problem soldering a dental instrument for my dad. I was ready to crimp with a telephone wire crimp connector, but my dad is old school and just had to use solder. So, I guess you can do it but it may come undone and cause you problems later.

Understood, I'll do the same.

Hold on, you're installing a Steve Wong chip? Then you have no choice but to install a working O2 sensor, or you'll get absolutely zero use from the chip, unless Steve re-programmed the default map as well. If you don't install the O2 sensor, then it'll run like you installed a chip that was programmed for 85 RON, and you will be not happy.

I hear you, I'll leave the stock chip for now and I'll replace it either with a new one or the old one if I can manage to get it out.

Thanks for your answers.
