What is the model or code of bosch oxygen sensor ? How much will it cost ?

Today I unpluged the wire (the pink color wire ) of oxygen sensor , then start my car . Everything is ok , and the "engine check" indicator is off :? Then I check the resistance between the wire of oxygen senor and car body. Found it is infinity or disconnected. Finally I check the outside of oxygen...

How is your fuel consumption now ?


Should I change my o2 sensor ? How much will it be ?

And should I use power steering oil only , or replace by automactic trans oil ?

Thanks

My 1.5AT eats a lot of petrol too, arount 15L/100KM! I think it should be about 9 litres reasonably.

Any successful work by changing o2 sensor or filter ....etc ??


It is strange when I turn on the engine , the fuel meter will drop a little within a few minutes.

Yeah.my car has done 3000kms only for the whole year. Sorry it is 3,000kms not 300,000 km.

I didn't change my oil for a year ,because I only drive only 3K km on it . Should I do it now or wait for 5k km to change it ?

I have done 2000km since I found that residue in the engine oil cap. Now the coolant level doesn't change much and can't find any residue in back of cap anymore .

Is this mean everything is ok ?

I think the water may come from the vatilation hose of engine cam cover during rain or humid weather .

Got parts from korea GM Daewoo for Lanos , so I can do the service myself.


DIY :P ( Waiting for next service due )

Good experience !!
