Hi Guys
I'm having a problem with my 2003 Subaru forester. When I push the accelerator to about 25% or 100% the car pulls well and accelerates at the normal rate. My problem comes when I accelerate at about 45% to 90% of the way. The car seems to loose power and seems to makes a slight jerking motion as if you were pumping the accelerator from 90% to 20%. I really need to find what is going wrong as it is killing me having to use 25% or 100%. I am fairly technically minded.
Fuel filters are clean
Car has about 97 000km on the clock.
Any help is much appreciated guys
