My 06 Lincoln TC sometimes has a intermiitent hesitaion at low RPM's when begining to accelerate after slowing down for a red light. It feels like there's a misfire then all of a sudden the motor gets momentum and kicks in. This seems to occur only once in a while. I'm getting poor gas mileage(12 mpg)as well. I've changed the spark plugs and filters and no codes come up when scanned. Thinking that possibly may have a coil that is starting to go bad or a mass air flow sensor problem. Any input would be appreciated!!! Can reach John at DPCLOSER1@GMAIL.COM

Could be a coil or coil boot. If you've changed the plugs and not the coil boots, you simply must do that before anything else. As soon as you pull those coils off, the boots crack and leak spark.

Could also be a mass air flow issue or an air intake / vacuum leak issue.

All those items are key to smooth operation. You should be able to monitor it all using a quality OEM style diagnostic tool.
