1) ABS indicator light is on even after I have replaced the ABS sensor as told by workshop, they expect the ABS ECU board to be faulty... do you think this is the problem?

It sounds like your shop has not diagnosed the problem, but are throwing parts at it. Is the light on all the time? An intermittant ABS light is also a sign of a charging system fault. An ABS wheel sensor problems usually shows by having the ABS engage at very low speed, but no warning light while driving. It sounds to me that proper diagnosis is your first priority.

2) Aircon not cool sometimes but when i restarted the engine, then OK. A/C compressor replaced two days ago but problem still persist. Could it be the problem of cooling coil?

3) Sometimes NO Air or A/C come out from the centre,only from the sides when accelerating. When accelerator was released, air started to flow.

For those two questions, you should ask Steve Brotherton, as his knowledge of AC systems is nothing short of amazing. Make a thread with the heading "AC problem in 1994 C220/280." BTW, please let us know WHICH car you have, and the mileage. And is it the same shop replacing the AC compressor? If the problem is persisting, again your diagnosis work is incomplete.

4)Engine jerk pretty hard when gear is shift to D or R and the car started to shake pretty much, engine become not stable.. and stop sometimes

Could be many things. Is the check-engine light on? This car is subject to wiring harness problems, and they cause misfiring. Is the tune-up in good shape?

5) The reverse gear seems to reponse very slowly. It will take the car to start reversing only in 3-4 seconds when gear is in R.

That's a sign of tranny problems. Might need a complete re-do (about $1500-1800USD) or just some bits. Most likely the former. Again, no idea of your mileage.

6)Noisy sound from gear knob when the car is accelerating, the gear is loose when feel.

Shifter bushings or tranny problem. I'm not much help with this one!

7)The brake light from the right tail light seems to be dimmer compare to the right. Replace with several bulbs but still the same.

This sounds pretty obvious, but do you have the rear fog light on?
