today my engine crackles in acceleration and performances are poor over 140 km/h.
Pression and control pressure are good, my injectors and o-ring are new, but after I turn off engine there is a leak in control pressure circuit, this value go zero in few seconds.
Clackling seems due to injectors, but how is possible ?

loss of power is over 3000rpm, but engine rumble even under 3000, the day before the engine run well to almost 200 km/h.

I don't understand if the problem is electric or it's a lack of fuel.

I solved the mystery, the sleeve of first injector is broken , then mixture on this cylinder is lean, temperatore is too high and this bent electrode.
