There is a fuel filter on the 04 but not the 05+. Have you tried cleaning your throttle body? usually the cause of the start/stall problem.

could be the MAF

whats the best way to clean off the throttle body? any way to clean off the MAF before considering replacing?

Yes, you can get both of those cleaners at any parts store.

My car has the same problem unless you give it a tad bit of gas on start-up. Im gonna try this now.
