Code P0031

Okay I got this code the other day and I've already got a new o2 fitted and I've noticed that the engine light hasn't gone away. What can I do to get rid of it? I've also noticed she's been quite jerky lately too. Any fix to this too

ecu reset.

unhook the battery for a couple hours.
re hook up the battery. turn to reds for 20 seconds so idle plate sorts itself out.
then start and let it idle for 5- 10 minutes.
dont boost it for 20ks.
slowly reintroduce boost.
keep fingers crossed
