rear 02 fix problem

[4g64terror]

so i got the spark plug anti-foulers, drilled one out, screwed it into another and then put them both with the 02 in the pipe....i installed a gutted cat off a 2g and now the car is throwing code 59 up...any ideas?

[RAZ_76]

No idea

I did this over 2 years ago and ive never had a problem. So i dont know what it could be. Try finding the resistor fix.

i was only supposed to drill the one anti fouler out right? not the other one too?

[mko]

yeah, just one!

btw, i got my cel on as well, and it was code 11 /obd1.5/ - rear o2 sensor

[4g64terror]

well its throwing the rear o2 code...SOOOOOO with that said, how can i test the o2 further to see what the deal is? test the voltage somehow to see what its reading?

[mko]

Just bought the components for the electrical o2 fix. Ill post some pictures later on when I solder all together

[4g64terror]

let me know if it works...im wondering if mine is so old and dirty if I should just let it stay in the airstream anyway...maybe its throwing the code because its TOO much of a voltage difference!

Well, I ll do the electronic fix, and you can try to block off the sensor completely of reach to exhaust gases
