I have a very light throttle missfire that is most noticable around the 1700rpm - 2200rpm when cruising. But it is possible to induce it, although not as noticable at higher rpm with a similar throttle position/angle.
If cruising at say 60mph on a very light throttle it will have a subtle missfire.
Slight pressure on the pedal causing hardly any rise in rpm and the missfire goes.
Drop the pedal back slightly and it returns.
Come off the pedal ever so slightly, almost to the point that you are off the throttle and the missfire goes again.
I managed to have a bit of a play today with a SmartBox VagCom tool and the load % when adjusting throttle was (seen in several Blocks 003, 054 & 084) :
Normally 1.18% at rest
It took what I thought was quite a bit of angle applied to get it to jump to above 2%, then it slowley stepped up in a linear fashion.
However, occasionally when going back into the same menu/block it would read 5.8%, a push and release of the pedal would see it drop to 1.18%.
Does this sound normal.
At the moment my current diagnosis points at MAF (maybe poor resolution for small airflows) or Throttle Pedal.
A TBA has made no difference
The car is running New Coils, New Plugs (gapped to 0.7mm) and New DV.
At any other time it drives fine i.e 1500rpm, foot flat (WOT) and it pulls through very smooth.
Also if in the missfire zone and applying any additional pedal pressure it then acceleraets out of the missfire without even a cough.
