Help required please
I have a 2007 WRX Hawkeye with a cobra exhaust and 2nd cat decat pipe (still got cat in down pipe), and it has been mapped by Racedynamix.
Today, I put £30 of v power nitro + into it then drove home 15 miles - no issues.
I went out an hour later and almost immediately it wouldn't boost, just splutter and kangaroo.
I could drive it off boost with light throttle control.
Anyway, I stopped, turned off the engine, couldn't see anything obviously wrong so started it to go home then a cel was thrown up.
It was p0037 h02s heater control circuit low bank 1 sensor 2.
This, I believe, just relates to the heater in the rear o2 sensor and shouldn't affect the drive of the car.
Anyway, I cleared the fault and tried the car, no cel but the code is back p0037 pending, and although I will try and boost, it still splutters a bit and won't boost over 1/2 bar.
Anyone got any ideas why the p0037 would cause the running issue or does it throw it into limp mode?
Also, does anyone know the location of the fuse for the rear o2 sensor?
Any help will be gratefully received.

Thanks for the replies all.
Once I got under the car the issue was blindingly obvious. One of the cable clips had broken and the sensor cable had been rubbing on the props haft completely cutting one of the wires in two. I soldered it back together and tested the car, all faults have cleared and the power is back.
I will now buy a new sensor to replace it and re-route the cable.
Panic over.
