Right here goes...
Got a 64 plate mk 8 jumbo minibus 2.2 125bhp (with adblue). Since I have had it is has always done a little misfire/stutter at 1750revs when accelerating lightly. Took it to Ford in Liverpool and they said it was the PCM learn (I think) and they have reset it. All good for a couple of weeks then happened again but I just ignore it now - dealer was useless and I couldn't be arsed.
Last week got the bus remapped to 180bhp - amazing difference and drives so much better. However when the misfire/stutter happens at 1750revs, the engine goes into limp mode. A quick turn off and on resets it but its constantly happening. The remap is great as it means I can use higher gears like you would in older vans but as I'm accelerating lightly and hits 1750revs it just cuts into limp mode.
Any ideas whats causing it? Anyone had similar issues?
Cheers in advance
