The first thing I would check is to see that all of the spark plug wires are connected correctly to the spark plugs. Maybe one of them has fallen off. If not, you may need to pull the sparkplugs and take a look at those.
Sometimes a vacuum leak will cause rough idling, check to see if a vacuum hose has fallen off.
Sometimes contaminated fuel will cause a problem like this...Did this begin to occur after refueling? Let us know how long this has be happening and how many miles are on the car.
Hope this helps.

The car has 174k miles. It actually starts when the car has been running for about 10 minutes so pretty immediate. I did have the spark plugs changed about 2-3 years ago but never the wires. If the wires are NOT connected correctly is this something that will be noticeable?
Yes it does happen pretty much all the time (before and after refueling). It has been going on for the last couple of years and will come and go in streaks but now its just constant. Should I start with the spark plug wires? what should I look for?
