check engine light 01 escape
3.0L auto 4wd
took it to autozone and it's some type of emissions code. dealer says cap was not installed properly recently. since then, i've filled up 4 times and even reset the computer only to have it turn back on an hour later.
also, i'm getting a small vibration which can get loud coming from the rear passenger wheel at around 40mph and at 67mph. at first i thought it could be a cv joint, but after lifting the rear and checking everything out, joints look and feel good. maybe possibly a wheel bearing?
