I have a Nissan Qashqai Year 2008 HR16.While driving about 20 km and engine reaches operating temperature, no acceleration above 3,500 RPM on 3rd gear, but if you put 4th gear or 5th gear, normally the rpm drop then you get a little more acceleration, again if it reaches 3500 RPM no acceleration. I depress and release the accelerator pedal several times during the 3500 RPM but the accelerator not response.You have to stop the car, put the ignition to off and back on but then it will take very long time to start engine.If the engine is cold it start easily,no lack of acceleration no problem at all, engine full power. This happen only when the engine reaches operating temperature after approximately 20 km to 30 km of driving.If you put the gear in neutral while the problem occurs that is the engine is at operating temperature, you can accelerate above 3500 rpm to 7000rpm very easily.I put a new battery. I perform Scan no fault found.Please help.Thanks
