Recently, my Santana 2000, second gear and third gear, has food to eat.

There may be the following possibilities.

1, the throttle line has poor aftertaste and elasticity and needs to be replaced.

2. The throttle valve is not working properly and needs to be cleaned or replaced. There is also a poor match between the throttle and the driving computer. You can go to the repair shop and let others bravely contact the computer to adjust.

3. The spark plug and cylinder pipeline of the engine need to be overhauled, so we can consider replacing them with new ones. Or the engine has too much carbon and needs cleaning.
