Hello there! I’m new to this forum and thank you for letting me join. I own a 2007 legacy, but not GT. About a month ago it started bogging down when pushing accelerator pedal. Right now it idles fine but a soon as you try increasing rpm it bogs with like a heavy bass sound. It barely moves when put in drive. I’ve trailered it to a local shop and they replaced spark plugs, MAF sensor, fuel pump n filter, without any results. They couldn’t figure out what’s wrong with it. I brought it home and took catalic converter off and no difference
check engine light is off
thank you for any suggestions in advance
