Hello CL members i have a lil problem i have purchased the OBX headers and down-pipe i have connected all the O2 sensors now my CEL light is on i have purchased the 18mm and 14mm fouler but the O2 don't fit neither. And that's the only one they have can anyone tell me where to buy the Match to the O2 sensor on a 1999 GS300. I also have looked on the forums but couldn't find any help

 

Do they remove the stock cat?

 

yes they doo the cats are deleted

 

by an O2 emulator and plug the holes :/ no cat=CEL

 

If you would like, I can send you a couple O2 conditioners that we use on the 2000+ Toyota and Scion cars. I haven't tried them on a Lexus yet. They require you to have the post cat O2 sensors installed and they get wired into them.

Is there one or two post cat O2 sensors?

If you are interested, PM me your mailing address and I will send them out to you on Monday (I'm out of town til then) so you can try them out.

 

if i take your offer i wont need to buy O2 foulers?

 

Does anyone know witch O2 needs to have the Fouler on or it doesn't matter?

 

If our O2 conditioners work properly on your car, you will not need to use a spark plug de-fouler to space out the sensor.

The Conditioner gets wired into the signal wires on your O2 sensor and modifies the signal to put it in the range the computer wants to see.

 

Can you show me a pic of the product and how much it will cost and where can i buy it from also are you sure this will fix the problem?

 

I don't have any pictures of them off hand. If you want to try them out I will send them to you for free and if they work let me know so I can add the GS300 to the list of applications. If not, your not out anything.

They are normally $15.00 each on our webstore. Here is a link to the install instructions:

Email or PM me your name and address and I will get some made and sent out to you.
