"SERVICE ENGINE SOON" light!!! Please help!!

[03MACH04SVT]

I installed a bassani catted x pipe on my '04 cobra back in december.
it all seemed fine but now the "service engine soon" turned on.
the trouble code that keeps coming up is:
P0153, O2 circuit slow response (bank2, sensor1).
I have tried turning of the bank2 O2 sensors and it works for a while and then it comes back on.

i put the 24" O2 sensor extensions on the car, the only thing that i can think of is that the extensions are too long and this is whats causing it. idk?

any info is appreciated. thanks!

kept happening to me. Unplug the battery for a couple hours, and it should go off. If not, I have been told that it will turn itself off after the computer learns the new reading. It may take 3-400 miles to do so.

Mine did that too and I had a catted X with the extensions. It would randomly come on when just cruising, but for some reason when I got into boost it would go away. Now its been off for about 10,000 miles so yours might turn off soon. Just be patient or try the battery thing. Good luck.
