i had the cat romoved and had a gutted cat put on now the mecanic said i will need to put on a resistor into the post cat oxy sensor now i was wondering if any one herd of this or knows what resistor to put in to slow the sensor down??

 

no one??

 

With a gutted cat or test pipe, the secondary o2 sensor with throw a CEL because it thinks your cat is not working. You have 3 options - live with the orange light staring back at you, make a mechanical o2 fix out of two spark plug foulers, or you can get an electronic o2 simulator and wire it in so it tricks the o2 sensor into thinking the cat is working properly.

 

this o2 fix out of two spark plug foulers speak more of this fix how easy is it or would it be more wise to get the simulator.

 

Personally, I think the mechanical fix is the easiest option. The basic gist of it is, you pick up two spark plug anti-foulers from you local auto parts store. Then, drill out the hole in one of them with a 1/2" drill bit. This will widen the hole enough for the tip of the o2 sensor to pass through. You screw the o2 sensor into one of the foulers and then screw both foulers into the cat/test pipe/etc. Since the o2 sensor is moved back from the direct exhaust flow, it "thinks" the readings it's getting are correct and the CEL is eliminated.

Since you're using a gutted stock cat, you may only need one fouler for this to work. There's a lot of information available online on building this system. Search around. Good luck.

 

thanks that helps alot i will have to try it this weekend

 

i found this http://forums.evolutionm.net/showthread.php?t=114931 i'm guessing it does the same so i'm gonna try it later this week

 

I could not have said it any better myself, i tried telling friends about the same thing in teh past most have relocated it. but great 2 go

 

wow i installed the fouler wednesday and my check engine lights been off for a whole day of driving i am amazed. thanks for the ideas

 

we are so happy for yu, great. yu see as told since with a freer flowing cat, the O2 seinsor is in a direct flow of exhaust air, by adding the foulers it takes the sensore out of the direct low of exhaust air and minimizes it into something it normally is in. LOL This just lets yu kno HOW much yur catalytic converter restricts lol.
