Pleanning on doing a leak off test at the weekend, but thought i'd see what the live values were from the IIDTool. Whilst driving they all report 0 so signs are good, however on idle a number of the cylinders will report up to +655mm3. This also happens on very light throttle with little load.

As soon as there's any load or a bit of throttle added everything returns to 0. Does this sound right? Has anybody or can anybody check if there's does the same?

Had a similar question which Mikey explained very clear

^+1 for the above thread.

I think you had better check those values again as +655mm3 is a tad on the high side

Any value at tickover above +2 or +3 should be investigated, as it's probably indicative of an injector on its way out.

Normal values should be a max of +1 to +2, with a Zero or a minus value denoting a normally working injector.

All values will drop to zero under throttle.

Do you get any judder or lumpy running at tickover?

Everything seems fine with it running, I'll test it again tomorrow and log the data to make sure i'm not being a complete muppet. That's assuming i finally get the bathroom finished which according to SWMBO is more important.
