Hello.
My son have a 2000 s600 N/A .
It miss at least half the power and are slow on trottle. I have try to borrow trottle pedal - trottle house etc. From my Cl 600. No luck.
I also got a fail on o2 sensor nr1 engine bank 1 (the engine was slow before the 02 fail) The car have 4 cats and 8 lamda sensors..
Can some body tell me what side bank1 is? Passengers side? And is nr1 lamda before cat from the 3 cylinders in front or rear? Or the lamda after cat?
It is a left steering wheel car. Do anybody now if the trottle back in the exhaust pipe is open or closed when its activator is not activate?

More likely it’s the coil packs or voltage transformer on top of the engine
you will usually get misfire codes If these parts are bad


it can also be a Bad Electronic accelerator pedal

 

Hi.
I change the trottle pedal from my cl600 who ran fine with the s600 trootle pedal.
No misfire code. Just one lamda sensor fail code.
It is also little low on rpm when standing still in drive (500rpm).
No misfire.

 

Ok if no misfire codes then get all new lambda sensors , they are old it’s time to change them

The shut of valve in the right exhaust pipe is normally open, and is supposed to close when in the 6 cylinder curt off mode, to keep the O2 sensors hot.
I deleted the the 6 cyl shut off mode long time ago, as it is troublesome, and the fuel savings are negligible.

 

Ok
So the trottle in the exhaust is closed at idle and low rpm.
Is the vacum clock aktivatet on syl. cut or is it activ when it shal go on 12 syl?

detail your profile please.
read again what i posted: when running in 6 cyl mode the valve should be closed.
If you search my nick you will find advice on deleting the cylinder cut off feature to full time 12 cyl operation.
