DIY: Mechanical O2 sim

Ok...I got this tip from some of the local car enthusiasts...and this is one cheap O2 simulator.

It works, and there is no need to cut any wires or anything...very easy as well.
I personally have driven about 300 miles since, no CEL. So anybody who wants to run a test pipe...here is the mod you should do to stop the CEL...don't bother with the electronic ones with only some of them working...and not working all the time. These pics are from it being done STi, but I did it on my S, works just the same.

Those are the Spark plug, Anti-Foulers you'll need to do this..just pick them up at any auto parts store

I work at an exhaust shop and made a test pipe for my can. Had it in for 2 weeks now with the spacers and have yet to throw a check engine light.
