O2 sim using spark plug non foulers?

[bluex]

Anyone done this on a GMT400? PO cut the cats off my truck and I'd like to get rid of the CEL. Seems like all the electronic gizmos are not sold anymore?

I'm probably going to try this, since it should only cost about $5?

Let me know how it works I'd like to do it to my 98 also.

Yes you can use spark plug non fouler's on the rear 02's to keep the Service engine soon light off, I have a set of them on my DD 96 right now.

no cat on my 96 and the CES light isnt on... they have to plug into my truck to do the sniff sniff test and it passes every time...

That's great!

They didn't work on my 98, but when I had that truck I was an inspector so it passed anyways.

Well didnt work for me either, light came back on in less than 50 miles. I havent checked the code yet, but I'm sure thats what it is.

I drilled all the way through one non-fouler so idk if that has anything to do with it or not. I didnt have time to measure the O2 sensors tip before I drilled it. Maybe if I hadnt drilled it all the way out it would have worked? I guess when I have some time I will data log the sensor and see if its even making a difference in the readings.

just get a tune, it will disable the code all together, no sims, no non-fouler rigged setups, you wouldn't even have to have a sensor in there if you don't want.

Done it on my S10. No light

its not the cheapest route but they still make the simulators .But if was to do it all over again I would just get a tune.
