99 lincoln towncar missing at idle, when accelerating it's more like a stumble, like running over rumble strips along the road side but not constant, check engine light is on, then will start flashing. Mechanic couldn't retrieve any codes when he hooked it up. Mechanic has changed coils, plugs, wires, injectors. Still having same problem and i'm out of money can anyone help please.

Go to Wal-Mart or Auotparts store and buy SEAFOAM. This will clean & clear the crud off of your O2-sensor. This should strighten your problem.

I have a 2003 Nav with the exact same problem. I've found it diminishes when taken out of overdrive. Also it's intermittent but more towards bucking. Sorry to post this under solutions.
