Hello all, I have a 99 outback with a 2.2l swap. The motor has 180,000 mi, and chassis has 205,000mi. I was having some idling issues, so i replaced the fuel filter. Was easy enough. Put some new gas and an injector cleaner in it. its been a week and still drives like its thirsty. Can someone tell me if i should look at replacing the in tank filter, or am i missing something.
Thanks
