my ducato has developed a fault whereby the engine appears to be missing or misfiring. Use of the throttle makes very little difference and the van will not accelerate. My mechanic has no diagnostic equipment for the electronic side of the vehicle and thinks it is a sensor or similar fault, as checks reveal it is not misfiring but has no uplift on the accerator. Anyone have experience of this???
Further we think its something to do with air/diesel mix maybe???

problem solved. EGR valve stuck.
