I've searched. Trying to find info on the non fouler Cat delete. Just wondering at this point if steel wool needs to be stuffed into the book fouler housings to truck the PCM? Or just screw them on... Anybody know of a thread on this non fouler Cat delete? Thanks!

 

That has been around a looooooong time.....Google search would've been quicker.

 

Thanks, you'd think. I did just find it, on here. No mention of steel wool. I did see something about steel wool, but can't find it again. I guess I'll try without it.

 

What's your current setup? No cats, cats gutted, cats drilled? Spacers in O2 bungs? O2 sensors in free air?
Was there a problem you are correcting by modifying the cats, or are you changing exhaust for other reasons?
Do you have a OBD tool that can read A/F ratio?
Don't mean to ask endless questions, just trying to understand your situation so we can offer options.

 

Thanks, I don't mind the questions at all. Glad to talk with someone who knows something! I pulled the cat out and replaced with pipe. Getting p0420 code once in awhile. Drives fine. Pulled the cat because I was having a undiagnosable issue, and was stuck in the bush, grasping at straws... There's a thread "craziest problem ever" on this, just FYI. Turned out to be a sensor splice shorting out at the back of the engine on the tranny harness, maybe due the this past summers heat wave breaking down the wiring loom.

No scanner to read a/f. Stock engine, although it's a propane dual. O2 sensors are stock, don't know if they have spacers. I believe you can say they are in free air. They're installed still, with pipe in place of the cat.

Thanks!

 

Need two non-foulers, drill one out, all the way thru, thread it onto the O2 sensor, screw the other non-modified non-fouler onto that one, then screw the whole thing into the exhaust. (these go on the post-cat sensor.) Should solve the issue.

 

Thanks again HeyYou. That's simple.

 

If you have not ordered them yet ebay has them that are already drilled out. It was 10 bucks for it and it cleared the cel for me.
