Hey guys I have been getting a PO420 cell alot lately... is my cat pouched??> i have had a zzp 3inchdown pipe on for like a month and a half or so now.. and now i am starting to through this code.. any ideas?

 

You are fine, car throws that code with the ZZP downpipe all the time.

Car doesn't like hi flow cats or no cats

 

Yes , zzp stupid downpipe will throw the code when the weather change but dont expect them to do anything about it . all there going to do is try to sell you there tune. When the weather gets back to normal the cat will fix itself or just delete it in hp tuners that code means nothing.

 

alright.. thanks guys, i have been clearing it with my intercepotors anyways, for the time being...

 

have someone with hptuners disable the rear o2 and that code will never ever show up

 

your car wants to smoke a doobie

 

where can i get a doobie for my car Area 47?....i've heard it adds another 10hp an makes it sip gas like a MF
