Catalytic convertor ??????

[gwgautney]

so I have check engine light on in my 06 ram 4.7. I had codee read and they told me my bank one back pressure was below thresh hold . They suggested it was catalytic convertor I wanted some insight to se if it could be anything else. Along with light the truck idlesrough at red lights and the rpm s drop to about 500 normally at around 700700.occasionally

Occasionally it feels a little rough when driving but not terrible for the most part it drives pretty smooth any ideas

Sounds like the good ole P0420/P0430 codes. Did you actually get the codes from "they"?

Could be numerous things from bad cats, leaks, sensors but bad cats is a good possibility.

I did not get code number s it was advanced auto parts was going to go and have them pull it again today after work and when I got in truck the light was not on I guys out reset itself. I just wanted to make sure it wasn't possibly o2 sensor before I had cat changed

Just curious its there anyway to do away with catalytic without throwing codes all the time

If its the P0420/P0430 codes, it's gonna be the converters. Because those are the codes I got right after I took them off.

You can run non fouler's on the rear o2's or if you have a programmer that has custom tuning options then you can turn the rear o2 sensors off via custom tune.

There should be a few threads in regards to doing non foulers.

I run nonfoulers no CEL here!

 

[gwgautney]

what are non foulers

Yes!! What are "non foulers"? I used to get those codes too but replaced both up and down stream o2's and havent had the issue again. But i think they trick the PCM into thinking the o2's are being used even when they in fact are not??
