if memory serves me right the rough idle problem on my legacy started about the same time that I replaced the fuel filter...give or take a few months. Forgot to document problem...so not sure. I used a cheap autozone part. I am wondering...could it be bad? What brand of fuel filters are worth paying for? not wanting to spend an arm, leg and two chickens for OEM filter.

I've had great luck with Purolator. I usually get them at Advance Auto Parts. They're about $15.

 

Supposedly, the OEM is Purolator, as is the oil filter.
