The rpms at which the car holds back are not fixed. One minute its from 3500 rpm, the other it's from 5000 rpm. I have the feeling (but cannot prove yet) that it happens the second the fuel system goes into open loop.@Sgt Nuts
Is this holding back at 3.5K rpm every time now?
Have you got any way you can check the ignition timing advance?
Yes I have. The resistance measured is spot on with the specs in the manual. When I backprobed the connector with my dvom and measured voltage between signal and earth it gave a solid pulse while cranking so I have no reason to suspect the DTC. If it where faulty I would expect difficulty starting the engine altogether.you got the old crank sensor on still?
At idle the 2.0 16v should be between 320-500mbars so 400 should be right within spec?@Sgt Nuts
400 mb vacuum at tickover???
650-700 mb or 20 inches Hg is normal.
Have you got a real vacuum gauge you could attach to that carbon canister spout?
this may be stupid compared to everyone else's detailed analysis but have you had your battery load tested? can you try another battery?
