P0159 with foulers

[b00stedgt]

I have used 02 foulers in the past to get me through emissions test in ny but tonight I threw a p0159 code. Has anyone ever gotten this code when using the foulers? I am thinking about drilling them out to get some more air flow to the 02 sensor. At this point I'm just hoping that I don't have to put my stock manifolds back on. Anyone using foulers and have gotten this code, please chime in.

Take them out and clean them up, they will be full of carbon. Took about 2 years for my foulers to throw that code but after cleaning twas fixed it.

Did you have the same code? I figured that I would have to drill out the fouler to get more air on the o2 sensor.

When I first got that o2 circuit slow response code on my pickup I just kept driving it and the code went away. I also didn't let it idle much on startup and it went away after a few cold startups.

Will the CEL on our cars clear itself? I thought the CEL will only turn off if you clear it with the SCT

 

[Tbone]

Yes some will. After so many startups and drive cycles if everything checked out it will turn off the cel.

If your needing to get through emissions soon, I would clear it and start driving a lot of short distance trips, cycle it as much as possible after clean or drill out those foulers. The air temps are up over 45deg so that should help it reset quicker. After you do the clearing and have run it through cycles, use your SCT to check for codes, then get through emissions as soon as you can, sometimes these codes come back after a short period.
Another code that releated to the use of foulers is one that says "catalyst converter efficency below threshold" you get this also when the foulers are full of carbon.
