When my car is sitting idle at stoplights it putters and idles rough and feels as if it's about to stall. When I am driving normally it is fine. Maybe I need a new fuel filter?

GOD... I love all these people with magic balls.
you haven't gave enough information for a good Diagnosis.
You need to bring it to a Qualified ASE Mechanic or you can spend a lot of $$$ with your psychic.

I have this problem also. As far as I have read on the internet, your vehicle (and my vehicle) may need to have the EGR valve replaced.
The EGR stands for Exhaust Gas Recirculation. Exhaust gas is routed back into the combustion chamber because the exhausted air is much hotter than the intake air (try touching a muffler sometime). By sending warmer gas into the combustion chamber, the air/fuel mix does not have to do as much work to heat up, and your engine runs more efficiently.
EGR serves one purpose and one purpose only. That purpose is to reduce Oxides of Nitrogen (NOx). Under normal combustion, Nitrogen (N2) and Oxygen (O2) in the air and Hydrocarbons (HC) in the fuel combine into water (H2O); Carbon dioxide (CO2) and the Nitrogen remains unchanged. Under very hot combustion temperatures, the Nitrogen reacts with the other two byproducts and forms Nitrogen oxide (NO). After being released into the atmosphere, it picks up another Oxygen and becomes Nitrogen dioxide (NO2). In the presence of sunlight, it combines with other compounds like Hydrocarbons and forms Smog. Since exhaust gas is inert (very stable) it doesn’t burn again. So by being introduced into the combustion chamber, it will lower combustion chamber temps enough so that the Nitrogen doesn’t react with the other compounds and is passed unchanged out the tailpipe thus not contributing to smog. Now, since exhaust gas doesn’t burn, it doesn’t exactly help with combustion. At higher RPM’s, this really isn’t noticable, but at idle, the reintroduction of exhaust gas will cause a very rough idle and can cause stalling if to much is introduced into the combustion chamber.
As far as fixing it yourself, it's an electronic part. I'd say you're better off having a mechanic or experienced friend do it for you.

It could be a few different things, but probably not the fuel filter. Could be a Vaccuum leak, so this would be the first thing I would check. Try to ask a friend who knows about cars and good luck.

fuel filter will not resolve your problem it could be alot of things the best thing to do is a engine diagnostic to find the real problem. you could have more than one. and they only way to find out is to take it to a mechanic who knows about diagnostics and how to repair the car correctly. see it could need an iac module a good tune up, so instead of second guessing it is better to take it to a repair shop.

Not likely the fuel filter. Could be several things. Timing may be off. Plug or plug wire bad. Air filter dirty. Carbuerator gasket(s) may be worn out. Start with air filter then plugs,wires then timing. Bad gaskets can also make it suck air in through tailpipe.

i own a repair shop,and its possible you may need a real good tune up on it,and also maybe a new gas filter,there are a lot of things that could cause this to happen,a clogged up egr valve will also make it do this,or a bad vacuum leak on it also will do it,on today's cars there are 20 different things that can cause it,so you just about have to check everything on them to find a problem now days,but if you,ll take your time you will find it,,good luck i hope this help,s.,,PS if you disconnect the egr valve ,and it smooths out,you need to clean it out good ,,and happy thanksgiving.

Timing might be off or IAC control stuck.. The make and model of the car would be a big help!
