i was reading on 84b18's thread and someone on there mentioned a gapper for the o2 sensor. can anyone send me a link as to what it looks like? i want to go to autozone and get one and i know for a fact they wont tell me the right thing.
If anyone could do this for me it would be much appreciated.
**also, idk if i have to thread it all my self but what sizes are they? how to i make a thread to go into the test pipe? orrr is there another way of doing this without me having to thread anything(like a item i can buy).

again thanks s2ki

Anti-fouler?

 

Use a spark plug anti-fouler with the center drilled out.

 

if you use a defouler won't that cause the O2 sensor to read inaccurately and possibly cause your engine to lean out too much or run too rich?

 

i did the anti fouler, drilled it out, and so far its worked for a day now, i do fear it running to rich, but we'll see. I do smell alot of gas out of my exhaust now, but thats to beexpected because theres nothing catylizing the fuel..
has anyone had a problem with their test pipe and using a anti fouler? im curious to know if it actually works permanetly.

 

I've had a test pipe on for a year with the defouler mod on it and i've never gotten a CEL.

 

the first o2 sensor is the one that adjusts a/f ratio. the 2nd o2 sensor right after the cat is the one that checks if your cat is working properly. you will not run lean because of this.
