I had this happen last spring a couple of times and then it just stopped; it has now started again.
Basically as I am driving (whether just starting in 1st or 2nd or cruising in 4th or 5th) the car starts to stop, then surge, stop, surge etc.
It feels like there is a complete loss of power to the engine, but there isn't because it is still running. I.e. if I pull over it is idling fine. Occasionally the 4WD light comes on when this happens, but not all the time.
When this happened last year I thought maybe dirty AFM's or dirty fuel. I initially thought AFM's as there was a heap of pollen around the first time it started happening. But this wouldn't account for the 4WD light I don't think.
Maybe an electrical issue with the ATTESSA?
It's odd though because I can still have my foot in the same position on the accelerator and power cuts, then surges back on.
Any thoughts?
