Long Tube Headers and Engine Light

[Wilson]

I put on SW LT and the dash light never came on. I took the cat's off and shut the o2 censer off. I have the cat's for sale

won't pass inspection

hey guys, i'm in new york and finally going for my emissions test and she won't pass , swheaders , highflow cats and a 5 star tune, put the stock tune back in drove 20 miles and got the cel , code say's front 02 sensors too slow, i forgot to write the code # down but remember it saying , fronts to slow, so i think i'm screwed, changed the oil, 200 miles ago, air filter is clean, and monitors are throwing the light, any suggestions or do i have to go back to the stock exhaust, this sucks, i read a thread a while back on jim d'amore in new jersey may have a fix , has anybody spoke with him??? i will call him on monday and see what he say's.

Put the tune back to stock and drive it so the sensors reset

Tune won't help if the air-fuel ratio sensors are already switching slowly, basically you need new sensors and then run the stock tune while it's getting tested, unless there's a way to temporarily revive air-fuel ratio sensors, you could just get a new set of air fuel ratio sensors, swap them in for testing then take them back out and put the bad ones in for driving until you need to test again

He did.

I heard something about an "Anti spark plug fouler" screwed onto the O2 sensor then that screwed into the cat would trick the system.
Not sure if that's works or not.

Opps didn't catch that.
