Hey Guys,

as all the porsche part places are still closed for holidays and I need a new oxygen sensor, does anyone know what other cars may share this part or what the bosch/denso replacement part number is??

cheers!!

Spence, the one I have from a Porsche parts vendor is Bosch #13913, for my '87... good luck!

thanks alot Ked,

I have read you can use pretty much any 3 wire oxygen sensor, you just have to solder the plug on. I found that the 13913 is a universal sensor. This will cut the price down under half of what the Porsche Stealer wants!

thanks again!!!

I think the 13913 p/n is correct.

What I did was cut the lead off the old sensor and solder each of the wires to the new sensor. Each connection got a piece of heat shrink tubing over it, and then I put one large piece of heat shrink tubing over all of the connections. It's been a couple of years, now, and no problems.

Good luck.

ahhh cheers thanks scott, my car has all of sudden started doing the hestitation just under 3000rpm and hunting at idle. This was after I took my cat out and replaced it, I'm tipping I must have damaged the o2 sensor as I did drop it accidently.

Spence, there is a possibility that your drivability issue is related to removing the cat in a different way... the Motronic system learns & compensates for the state of tune of your engine (& driving style & conditions, to some extent). By removing a relevant component, the baseline has been changed (cat: backpressure & temp). So, it is worthwhile disconnecting the battery for a minute or two to reset the learning process of the Motronic system & see if that improves things. You'll do this anyway when you change the O2 sensor, and if you have over 60K mi on the sensor, it doesn't hurt to change it anyway. a pro tuner may shed more light on this matter... cheers!

cheers ked, if that solves the problem, I'll post you $50!

someone said it maybe a faulty dme relay too, I'll keep you posted.
