Hi All,
I'm not really that knowladgable in engine diagnostics, hence would like to seek your support in interpreting the injector correction values for the engine in my C4 Picasso II.
The reason why I started looking into those is that I have a feeling I have a bit more vibration at idle. It's still quite gentle, but feel like it's more than it used to be. I checked injector correction values (my ECU doesn't show actual value of fuel correction). Checked it twice each time after the car had been driven for quiet a while, so engine was well warm. When adding those the value is not that close to 4 or when applying a logic of what's above 1 subtracting from what is below 1 -it's not really close to O.
I measured it one more time, but forgot to write down results, but remember that 2cyl was around 1.1 and 4th cylinder was apx 0.89.
1st check:
1cyl: 1.03
2cyl: 1.077
3cyl: 0.952
4cyl: 0.929
2nd check:
1cyl: 0.999
2cyl: 1.069
3cyl: 0.975
4cyl: 0 936
What's your view on the corrections, anything to worry about or look into immediately? When driving all seems to be good, do not feel less power, fuel consumption is more or less the same, maybe slightly higher but at the same time my driving patterns differ quite a lot recently.
