I did a/f with the code and without exact the same as well as timing datalogged.

Are u sure its the p0420 code that u have? u could just have a bad o2 sensor this mod does not fix bad o2 sensors just tricks them.

Went about three days with this mod and got P0133. Thats driving though town as well. It doesn't work, and I'm going back to stock.

You have 3 options.

1) Try this again.
2) Buy a stage 1 (new or used)
3) Go stock.

I would try it again, then buy S1 if it still won't work for you.

Just curious, what DP do you have? What 02 sensor?

I got a code the other day when i went on the highway with this mod, and since ive reset the comp it hasnt gone back on in the city. Dont know why getting on the highway would trigger it, opposed to city driving. it went on while i was excellerating not cruising.

Lagzilla · 10-13-2005, 01:41 PM

ive got the non fouler on but the code comes on anyway

jmihalchik · 10-13-2005, 07:45 PM

wow how many times does it have to be said, the only code this gets rid of is p0420..... If u are getting a p0133 code look for exhaust leaks.

I allready went back to stock, reset the pcm and got rid of the code. I have the Maxxfab 3 inch, modified with a cut-out. Should I just wait untill I save up some pennys for a stage 2? I'm a 05 BTW.
