Noticed today that every now and again the cars idle starts going up from 1000rpm to around 1400rmp and then back down again quite quickly, it carries on doing this for a few minutes. Looked at the power fc whilst it was doing this and the percentage for the injectors would go from around 1.6% to 0 when it did it but then would go back to normal and start idling at 1000rmp again....Anyone got any ideas of what it could be?
