I 'm really puzzeld by this one: some two month ago I had normal figures for the injector fuel comp. This weekend I started teh IIDTool again and now I have these readings:
Cyl 1: 654
Cyl 2: 1
Cyl 3: 654
Cyl 4 655
Cyl 5: 655
Cyl 6: 2
As far as I know Cyl 2 and 6 are normal, but the other are so far out range. Can't beleive that al at once 4 injectors are gone and all in exactly the same way . Is there anyone who's had the same and how has it been fixed?

I've just had the same thing with my Cylinder Fuel readings, a couple read normal at +/- 1 and the others are at +655!! The motor idles smoothly and runs fine, no adverse change in fuel economy.
I've also noticed that the 'high' readings seem to jump around from cylinder to cylinder, depending on when I've taken readings using my IID Tool.

Strange...

Bad for you and glad form me that I'm not the only one. Motor runs fine as well (idle and when driving), fuel economy seems to be a bit low (22MPG short trips). Discotiger where you able to trace it down and fix it?

or someone else who found a remdie

Not really worried about the readings as had the motor serviced last Friday and the mechanic said everything was running fine.
Just put it down to a glitch with the IID Tool or the electricery control units in the FF. Just had a new battery two weeks ago, so can't be down to low voltage. Will probably check again in a week or so, as I've got a new steering angle sensor to fit and am in the middle of sorting the rear wash / wipe unit. Got the wiper motor unit cleaned out and am getting ready to fix the washer leak.

As far as I know the two are not too shut: the readings should be between -2 and +2. Anything above is no good. And I thnink overfuelling in the range of my readings can't be any good if true at least when more fuel is injected (dilution of the oil in cylinders). But this I can't verify.. Is there someone who can comment on my thoughts? If someone has the same problem please let me know, want to understand what is going on and how it can be fixed

those 655 readings i have those also, have asked before on forums and no one could interpret them for me. asked a diesel place and told nothing to worry about . it jumps from cyl to cyl.
