Hey Nick, some of your font is blue, while the rest is black, and it turns my pointer to a finger when I scroll over it... Are you hacking the forums?

**TheOtherNick** · 06-07-2011

Yeah, thanks for your bank account.

P0420. Learn to love that code until you get an 02 sim or program it out

i refuse to like that code:P there a guy on here told me to do this

$5 o2 cheater/non fouler how-to - evolutionm.net

it takes someone with a tuner 2 minutes to set the code to no report and it goes away forever.

Right but if you have a '01+ car you NEED to keep the rear o2 sensor.

**Colossus** · 06-08-2011

Not sure where you getting at but mines an 01, before I did the non fouler trick i had the code, after install, nothing. Not sure even what year the OP's car is.

Epic Win. Just educate yourself first.

My vote goes to getting a powertuner or HPT and not having to rely on anybody else.

i have another exhaust from another grand prix so ill take the cat off that one since its too complicated with the o2 sensors. no one in my area carries a spark plug non fouler soo i cant trick it.

**blueguy** · 06-09-2011

YOU CAN BUY ONE ONLINE AND IT PLUGS IN.

From ZZP or any of the 3800 vendors.

Then it kills the code.
