Hey guys I no this is asked all the time

driving like my Nan

singnal so I reset the ecu and today my engine Light come on again and i checked for codes again and this Time got 44 or 45 it was o2 sensor rich
so I'm gonna change it when I have cash
and just want to no do u think this is why I get
such bad fuel econemy

if your o2 sensor is sending bodgy data, it could have you running rich, its an easy job to throw in a new one, car needs to be up on ramps, will be fight to get the old one off, and the new one goes on finger tight, then 1/2-3/4 tight with a spanner. when you put the connector on, make sure it cant move around to much, dont want it sitting against your exhaust manifold and melting. so cable tie it down.

the vn has the single wire sensor, but the guys at repco should know which one.

no guarantee its the whole cause of the problem, but it is defidently part of the issue and should make her run a bit better if its gotten that bad.

absolutely it will make a difference. especially if its throwing codes, definitely time to replace o2 sensors. if that doesnt fix it then replace coolant temp sensor next.

lets just say you want a good oxygen to fuel mix right? if ur oxygen sensor is screwed, then i guess ur not getting that optimal mix so your car won't run the way it should. my advice...change the sensor!

Ok thx I will change it when I get some $$ and I'll let u no what
happens and I have change the coolent temp sensor and thermostat
fuel pump sparkplugs oil coolent terminals and I have
cleaned the throttle body and this is all in the last month
