I have done the following tests:
1.Remove the ignition coil and test it with a coil tester - test faulty.
2.Check the fuel pressure - test Ok 25 - 30 kpa
3.Check the Air temp/Maf sensor the a ohm meter - it is within the specs.

The problem with this car was, the engine lack power, if you try to rev it , it will only rev up to about 2500rpm. Before buying a new Air temp/maf sensor , I have remove it from the airbox and clean it with carb cleaner.
This cure the problem, now since I have clean the Air sensor and replace the ignition coil and Plug wires, this
car is running excellent.

The customer is now very happy
