Rav4 Problem...Please need help!

[tommy1982]

Im having a problem with my 2004 rav4 1.8 M/T. Sa morning pag medyo malamig pa yung engine napansin ko hindi maganda or swabe yung pag timpla ng gas and clutch. Parang mamamatayan ka ng makina. Pero after siguro mga dalawang kalye magiging ok na timplahan nya. Aside from that,inconsistent yung power or hatak nya sa daan. There are time na ramdam na ramdam mo power nya everytime i step on the gas. Then,while driving minsan mararamdaman mo kulang yung power nya.
Kapapalit ko lang naman ng airfilter and sparkplugs. Im using K&n filter and the bosch platinum sparkplugs. What could be the problem? Please share your thoughts. Thanks!

Bro, kumusta condition ng fuel filter mo at fuel pump? Kailan ka huling nagpatune up? Nung nagpalit ka ba spark plugs na tune up din? Hope this helps.

Nas check na ba iyong engine timing ng sasakyan mo.

- nagpalit ka din ba ng fuel filter?
- could be that the spark plugs that you've used too are not compatible with the vehicle.

Im not sure kung need pa itiming yung model nung rav ko. Hindi din ako nagpalit ng fuel filter... Fuel ration is good,around 9-10 km/lit sa city driving... May effect ba yung pag papainit ng makina ng auto sa umaga bago i-andar?
