Idle, stuttering. Please provide rating for MWB 13/18/23.

Hello, I have uploaded diagrams in /viewtopic.php?p=138295 showing the comparison of the measurement blocks 13/18/23 for both cold/hot engine and active/inactive climate control. I hope that these diagrams will clearly identify the cause of the defect (irregular idle).

Thank you.

Okay, I can see that Zyl 3 consistently has a slightly high compensation amount, but it's still within the tolerance (+/- 2.8 mg, as I recall). Whether this is due to poor compression or partially clogged injectors, I can no longer determine.

MWB 18 and 23 are unremarkable.

The PDE-Check MWB should always be logged together with MWB 1, so that you can see the current RPM and (average) injection amount. The fact that only 2 MWBs (in addition to 1) are used is simply a system requirement.
