my toyota camry 2001 drags, no matter how hard i press the throttle pedal the rpm does not go above 2x1000rpm in drive mode(while driving) but rev well in idle(park mode) though the rpm is usually about 0.3x1000rpm, it consume fuel alot(about 1Lto 2km),emits black smoke. I have clean the airflow meter, air filter and change the fuel pump but the problem still persist.

Which engine? Check engine light on? If so, what trouble code(s) number(s) is stored.
Was there any recent repair work done prior to the problem your having?
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

1MZ-FE is not really known for exhaust restrictions, but it is possible if you drive around with misfires occurring or the fuel trim isn't being properly controlled. You could check exhaust back pressure with a gauge to see if you have excessive exhaust back pressure.
Could have a weak ignition system component(s) that shows up when the engine is under load. Misfiring will usually cause the check engine light to illuminate and the ECU to store misfire code(s). There are various testing procedures that can be used to test the integrity of the system, but special tools may be needed.
Could have a valve timing issue. You would need to confirm that by using a DSO to look at cam and crank sensor signals and how they correlate against a known good waveform or use a pressure transducer in each bank to determine if cam timing is correct. You could also pull the covers off and do a visual inspection of the timing belt and sprockets.
The fuel could be contaminated. You could have the fuel tested by a lab or you could drain the fuel and put known good fresh fuel back in.
Those are some possibilities to eliminate.
