san po kya may diperensya???
cumputer box?
Distributor?
High tension wire?

Have you replaced said high tension wires? Spark crossfiring can be felt all across the rpm range, not just at idle...

The Computer box would also be my last suspect... are you sure you cleaned the throttle correctly?

Distributor? coil pack maybe? I don't have much experience with that particular model...
