Hey all, I went out and bought myself a Purolator air filter and changed it last night. The original was all filthy and was an OEM subaru filter, so it wasnt changed for a good 20,000 miles. Anyway, after changing it I noticed my car is a little hesitant when idling with the heat on and when im at a light. Its not really hesitant but it was noticable and didn't do it before.
I didnt put the OEM back in yet. I will try it when I go home. Does anyone have any ideas, because im stumped
