Hey guys, newbie here.
I just picked up a 2015 WRX a few weeks ago. 60K miles. No mods done now, or have been done on it. Car was babied from what I can tell.
BUT, my issue is this.
On any sort of incline where I almost stop the car and put it in to 1st gear and start to feather the gas it doesn't seem to be totally responsive. I feather it and I'm getting hardly any power, then I hammer on it and finally get fuel and plug along up the hill. (Every day I do this to get in my driveway, because it is a small steep hill and every day it's an issue) This occasionally happens at a normal stop (no incline). When I give it gas, I get nothing in response for a second and then it catches up and I sound like a newb taking off.
From my research it seems like it could be a fuel filter issue. Found out the filter is basically a permanent attachment in the pump assembly and is a pricey job/part to replace when I think I only need the filter.
I called a subie dealer and he seems to think I shouldn't have an issue with the filter with that low of miles unless someone put something in the tank, or it was dirtied somehow, which I really don't think is the problem.
I've taken the hill assist on and off just to see if I was weirded out by the hill assist, which I am, but with or without it, it's still an issue.
No check engine light. No issues when driving or accelerating (that I can tell anyways). Just starts/inclines.
Any ideas? I've only had the car a month and this problem is making me NUTS.
