This happens to me lately. 2 scenerio.
Scenerio 1
Car stationary. Neutral gear. Accelerate, rpm rose to 2k and above, try to maintain at certain rpm, never release footing, rpm drop to below 1k then go up again like petrol suddenly never go in.
Scenerio 2
Car moving off from 1st gear, rpm reach 2k, power lost, car jerk, then move again. Change 2nd gear, same thing.
What happen?

==> it could be any of the several problems, ie spark plug, fuel pump, injectors, ECU, piggyback or fuel regulator (if u have any), etc etc etc...

Oil cooler blocked if u have any ?
The last time u changed the belts? 100k must change all
Happens at all shifts?
Sound like misfire leh.. sparks new? ... distributor clean? Spark plug cables good?

only happens at 2k?
scenerio 1 - if u neutral and floor does it still hesitate at 2k before climbing? or does it fly to 6000rpm?
yeah and it sounds like misifiring. u got piggy back pumping tons of fuel at 2k rpm isit?
check map sensor. maybe stuck at 1 reading. drop by my place lor if u want can scan ur sensor readings.

misfire. Something to do with yr ignition system. could be plug cable or distributor internal (coil/ igniter)
