Sir GA16DE comes with an Electronic fuel injection, meaning hindi po siya carburated.

The usual problem yan, kailangan lang linisin yun air mixture controller vavles niya. Sorry at nakalimutan ko na yun exact term doon. By the looks, mukhang madumi na siya at kailangan na linisin yun (fidc or fdic yata tawag doon). Pagbinukas ninyo yun hood niyo and youre facing sa engine sana left side siya pagtapos ng air intake manifold wih brown and violet/purple connector. I dont suggest for the first timer to clean this by themselves kasi medyo tricky. Makikita ninyo may 2 soleniod vavle doon, thats the one controlling the air mixture. One is the controller of air during airconditioner compressor naka on and the other one controls the idle. Its best to have to clean by a proffessional muna tapos tignan niyo kung paano gawin para sa ganon puede na ninyo linisin by yourself yearly.

Puede rin fuel pump pero bihira ito masira
