andrew- "run unrest"
siggy- the DME knows what kind of load the engine is seeing, when it is in gear it may be using differnet 'demand maps' which may be calling for different fuel pressures.
Not sure, but a caution that these can have complexities.
Still, you really need something (INPA, etc) that is telling you what this "miss feeling"really is....
