I know this thread is old but i just wanted to give an update on the car! Lol
I just finally got around to buying a new fuel filter for my car and installed it and now it starts right as soon as i turn the key!
But as soon as it started idling i saw that the rpm stayed at around 700 or 800 and once every now and then it would drop to 500 or so and then go back up to about 700! This never happened with the old filter tho? I double checked to make sure the filter isn't leaking or anything and everything seems fine
