Okei, I shall try all those things you have taken up

But since my Co gass % is sow high? And It uses so mutch fuel, what are the sympthoms? I thoug of what you sad, and if the fuel pressure is wrong, wouldnt that be noticed when i drive the car in any way?

Like I sad, I do not get any problems while driving, other then it uses mutch fuel. and the light is there, and my CO% is to high.
It should be 0,5% And now it is at 1,57 %

I'm no emissions expert, so I can't tell if increased CO is a sign of running rich or lean, but increased consumption points to rich. If that's the case you also might have a stuck open injector. Pull the spark plugs and take a picture of them to post here.

The plug color is normal, Light Chocolate brown. But her is the pic. (not the best camrea)

Are all of them the same?

Docen

Yes, All 4 !

Roto

Take the sensor out and try to rattle it. If there's something rattling inside than it's definitly bad.

Docen

Okei, I'll try that tomorrow, and I just have to say that I am very glad for your expertise !!

Thanks !

Docen

Hey, Nothings rattling inside of the o2 sensor !

On my car there should be a 4 wirring sensor, right?

Did I mention that my Driving computer is showing VERY high amount of fuel per 100 km. So mutch that in fact it's not possibel to use that mutch fuel.

And since I don't notis anything while driving the car? just that the chek engien light is there, and the Driving computer is over the hills !

My plugs seems fine. And like I sad, the car acts perfectly nomal while driving, I have to fix this because of the Eu-chek.

Can it be my cat is broken? exhaust leeks? something else?

Roto

Yeah, yours should be a 4-wire sensor. Have you tried resetting the ecu by disconnecting the battery?

Docen

No, should I do that whit taking the minus pole off in about 10 minutes? and then put it back on ?
