4g93 gdi engine starts
wont rev above 3000 rpm-starts misfiring
cuts off as i mash the x
sounds like starving for air
scan tool once said fuel rail sensor
swapped - air flow sensor, fuel pump & fuel pump (tank)
is there a fuel pressure boost pump on the engine?
Hi it sounds like your high pressure pump needs replacing. the pump can be repaired but you will have to find someone who knows about it, i fix a lot of them before. there is a spring that pushes out the piston in the pump so it can compress the fuel that spring losses its ability to extract the piston back out. i have pictures of one if anyone wants to see
fotos!!
Hi Joseph, I seem to have the same problem. Kindly share these pictures. Thank you

I can confirm with u that the end of the intake camshaft is broken...tat's why the fuel pressure is low.intake camshaft attach to the fuel pump to boost the pressure.for sure u won't believe what i say...i've seen more than 20 gdi model having tis problem..
This is true. My gdi had a broken camshaft. Started up but couldn't accelerate beyond 3rpms.

I know alot about these cars because i fix them, at the end of the intake cam where there is the star like end that engage the HPP high pressure pump, over time that gets worn out and the cam need replacing, so in other words the pump is no longer being pumped, so the car is running on the fuel tank pump if you turn on the AC and it gets worst them you should be looking and the gdi pump or the intake cam
Hi, I have a 2005 Mitsubishi Lancer Wagon, 4G93. It wont rev over 4000. It has no error codes, I changed the Mass Air Flow intake sensor and no change.
