Have you done anything with the idle air control valve? cleaned it/changed it/checked for cracks on the housing?

not yet, will check, thanks

 

the O2 VOLTS. BNK. 1 4,27 is ok? i think the o2 sensor should return values between 0,9-0,2 volts

HI I checked the idle air control valve - sbz008 3454, seems to be ok, housing also - not broken, clean.

 

Other thing what I tried to disconnect O2 sensor - read value is 1,8 - the engine was running - nearly stopped

but ACR did not found any error codes - is it ok?

 

Thanks,

Laci

the lambda should be constantly changing as you say, is the value of 4.27 stuck or does it go up and down, with the 4.27 being the max?

also the MAP sensor is quite high

The values at idle are between 4,29-4,31 if I give and release gas they are jumping form 0 to 4,4 - if I disconnect the lambda then I did not got any error - is it ok?

Thanks,
