Subaru Impreza, 2.0 litre GX Sport 2001 model non turbo
Loss of power at 4200 revs. Underload. Car keeps losing power when you put your foot down and revs hit 4200
If you put half throttle or keep under 4200 revs car runs fine. :feels like runin out of fuel,when i lift of gas its ok runs fine when i first start car,changed fuel filter put fuel cleaner in,stil the same,when i started the car in morning it pulls all the way past 6000,when warms up she starts her ************
