Hi,
My Forerster has developed a problem in which whilst driving at approx 4000 revs I get a kangeroo effect, surging that goes off after 5-6000 revs.
This has happened previoulsy about 18 months ago it went into Subaru at Richmond and they fitted new crank and cam sensors. The flat sopt was there slightly but has now come back with a vengence. The only other way of describing the effects are if some one is turning the fule on and off.
Normal driving , well pretty slow it runs fine but when I want it to go that bit quicker there it is.
It has been regulary serviced and I have recently swopped the sensors from another vehicle and the fault persists. No code is held in the ECU and only once has the engine management light briefly appeared but the memory holds no info?
The car has been fitted with an inline computer whilst driving and this again shows as no fault.
