Anyone who experience this?..rpm'drops when engaging clutch 1st gear usually and 2nd gear also.you have to put some'gas in order to get more rpm so that the body will not vibrate or the engine dies.clutch is still good coz acceleration is fast.the only prob is the rpm drops down when engaging usually in 1st gear n 2nd.i already clean the maf sensor and the throttle valve with the spray throttle cleaner.
