torque2006; speedyfix:

1.) its a nissan sentra LEC 16V twin cam engine.
2.) problems of the car:
- poor acceleration parang hindi makahataw other words "pigil manakbo".
- plug gets wet (oil); which cause hard starting after a long run.
- engine knodge after letting go of acceleration; parang nagcho-choke ang engine.
- high gas consumption ~5-8km/L

thanks!
