Figured I'd post this here too might get a little more attention:
I was previously getting that code saying that my passenger 02 sensor was shot.
I installed a new bosch for the rear corvette sensor and now I'm getting this code.
P0174 Fuel Trim System Lean Bank 2
Is it possible because I only replaced the one side that now I'm getting this code? Car has never thrown a lean code before, just 02 codes if I didn't let it warm up. The car was tuned a few years back at TTP, which is now closed.
Thanks in advance!

Probably not with that mileage. It's not the PCV valve itself but the hose connected to it that is prone to cracking and causing a vacuum leak. That would most likely also set P0171 but it doesn't hurt to check. Sometimes problems seem confusing and people start trying to over think without checking obvious stuff first.

A bad ground can do wild things to you ... Check on the rear drivers side head, and did the 01 have one on the coil bracket ? My 98 has 3 on the head... One broke a while back, and that's what it acted like...
