@ abhilash and philjo: i had faced the issue of sudden sluggishness while hard acceleration, only in 5 th gear sudden choking (sometime back) maybe before 10k service i guess) This was after months of pottering around in city, i just did some italian tune up and things were fine. No oil change was done during the period, so i dont think oil level is to be blamed.

If i remember correct, second time i just pressed the acc pedal completely (actually pumped it multiple times) when switched off and things were fine, so i think this has more to do with some silly electrical contacts in the sensor.

I remember Kuttapan facing same issue, which when reported at service station was rectified. They said they had cleaned up the throttle sensors.

If oil gets into turbo smoke will be white, not black. Black is when ignition is not proper, beyond the rate at which engine can burn.

@Eddy: Air filter can be cleaned, its a regular air filter element. Yes ideally blow air in the reverse direction of air flow through the filter, so that particles dont get further entangled in the element.
