Message	Hello guys, This is my second post here in twinturbo. My previous post was about starting problem which I solved. Well, now this is my problem. I have noticed that my car wont rev over 4500 RPM. At idle if I press momently the gas pedal there come black smoke from exhausts, but it evaporates immediately. Also when pressing gas pedal, the engine sound like it stalls and suddenly it rev. My fuel consumption is 20l/100km. The car is powerless after 4500RPM no metter in which gear. To make it easier for you guys to helping me, I have done these tests and replaced these parts: O2 senors are new. spark plugs airleak test made no leak all injectors are new DW 740cc with nistune ECU. PCV valves replaced with new also tubes. Thank you
