Default Help P0153?

Installed long tubes and an X with no cats. Tuned out both banks 1&2 sensor 2's. Running the rear o2's up from with the adaptor plugs from the LG kit. Car was running great. Took it out for a good drive, did some blasts, and all was well. Went WOT through to gears and brought it home. Just before I went to park it in the garage it started to run very rough. Threw code P0153 slow response Bank2 Senor 1. Car will start and run for a second very rough and die out?

Bad O2 on driver side??

2002 c5Z with LG street series headers X pipe no cats. Yellow terra rockers, comp springs, Ti retainers, and harden push rods. Zip tie mod and K&N filter.

Got the car up and gave it a look. I didn't see any burned wires on the sensors. Car and senors have about 10k miles on them.

Found the problem!
Broken Comp 918 intake valve spring!

Went With REV duals for insurance. Glad I didn't bend the valve.
