Hello guys im new to this club and im from The Bahamas. So im jus sayin hello. But I also have a problem with my impreza. Its sputterring and cutting off. I've changed the fuel filter, plugs and fill with fuel injector cleaner but no progress. But what I have noticed is that if I turn on the a/c the problem goes away whenever the compressor kicks in. The engine runs fine and smooth. When the compressor cuts out the problem comes back. Does anyone knows what the problem may be. Also there is no throttle response. When I press the pedal to the floor there is a flat spot, no engine revs or nothing. I hope someone understands me THANKS GUYS. oh and i have cleaned the throttle body as well.
