Hello guys, hope you guys can help with my problem of high FC.
My car is Proton Wira 1.6 manual year 1993 with SMT8T piggyback, full tank usually can go till around 550 KM. Recently my throttle body start having problem of lowered RPM when the aircond kick in. After installing FICD I notice my FC increase quite a lot, now full tank only manage to go around 400 - 450 KM. I tried taking out the power supply to FICD and surprisingly the FC goes back to around 550 KM.
Is the high FC really...
