R34 Gtt Dash Lights And Poor Fuel Consumption

[MrRx7s3]

Hey guys I have searched now for hours and hours and cant find anything relative to what my situation is, I have a r34 gtt series 2, and my tcs and slip light were on for a week or so of first owning it, reset the ecu and it went away all was good and now it comes up every now and again, the car doesnt missfire or anything and the engine light doesnt turn on at all, car idles fine, i have just replaced the spark plugs and the idle has gone up from 800 to about 1100 and also when you rev the car it doesnt go straight back down to idle anymore, it floats at about 1800 and then goes to around the 1100rpm mark, i did the ecu test and have a nissan conzult cable and I came up with error code 17, i think it said abs or throttle sensor or something like that, what could it be? its really pissing me off now haha lol, also im getting really bad fuel economy, 200kms to a tank, checked the o2 sensor on the conzult program and the voltage is around .80 on idle, could it be the o2 sensor, any help is really appreciated in advance, thanks.

Ohhhh and what should the air fuel ratio be on idle? also the car has a slight pop not a full backfire here and there, the car is running standard boost with a pod filter, blitz bov and 3" exhaust, it used to pop alot more regularly but i have tightened the bov a little since and its not as often so yeah.
