One of my friends had a problem recently with a GDI Galant (4g94). Basically, one day the car suddenly could not pass 40KM without throwing a check light. However the car was idling and could rev properly within park and drive.
Basically i had one of these cars and i suspected it was the filter however most mechanics wanted him to change the fuel pump. I did some research on this website and realized that many ppl have had similar problems and changed fuel pumps and got no solution.
Well it was the filter, i realize that in many posts ppl recommend to change filter first however many mechanics are quick to condemn the gdi fuel pumps when in a lot of cases the fuel filters are clogged!
My recommendation, any fuel problems, change the fuel filter first before working on the pump. The cheap fuel filters can be got at Sherrifs in south or Jurawan in the North. I think they are from israel, galant uses number 81. Cost is about $90
Originals can be obtained from Faiz and Diamond Motors, not sure cost. By the way i used to use the cheap one but i would change it once a year and i never got any issues.
If the filter doesn't help, try adjusting the fuel pump, i posted the method in another thread or try cleaning (Sanctifier's method)
The adjusting worked well for me, my car would get a slight drop in idle while in traffic, checked and fuel pump was running between 4.5 and 4.8 which is below the 5.0 MPA for galants, adjusted and problem went. Took 15 Mins.....
