Doesn't show up on mine at all. Had a really good search. What year is your car? Can you remember what heading it was under (I assume ECM ??)

Reset EGR adaptions again.
Think I need to set up a graph to monitor active readings to check whilst I am driving, but not sure what parameters to monitor. Anyone any suggestions?
Just tried a few whilst parked on the drive and the ECM Air mass/stroke is one of them and seems quite erratic. I assume this is the MAF sensor? Has anyone monitored theirs and is their trace as erratic as mine??

Hi

There must be some constructive ideas out there??!! On what to monitor??

Hi
Well after no ideas from anyone!
I decided to start checking things logically. Today was fuel pressures.
First graph I’d going up through the gears up a long steep hill. Second graph is along a level road. I was experiencing the hesitation along this stretch but the fuel pressures seem steady. I think from the graphs all is OK however I can’t find what pressures the fuel should actually read to compare against.
