During acceleration, vehicale hesitates then it feels as if there is only v6 power an no turbos. The check engine light blinks an eventually turns off. Once coming to a stop an coasting it shakes violently.

I took it to Ford an ford replaced the fuel pump, turbo & water pump.

The codes say it's the #2 coil but it's been replaced a lot an does fix the issue for a day or couple hours, replacing plugs doesn't seem to solve he issue.

This is a 2013 Ford Taurus SHO (interceptor) 3.5L TWIN TUBRO, 74k miles.

This is a actually police vehicle not just a interceptor, the vehicle continues to have issues during pursuits. Luckily when I need it it's worked I.E. (140 mph pursuit). I'm trying to see if anyone else may know a solution.

Could it possibly be a vacuum issue?

Mods, please move thread.

Fuel injector is usually the cause in these cases, where a misfire is indicated but plugs are uptodate. Coils rarely rarely fail. Also turbo-related piping/connected to the boost solenoid atop the manifold, may not be secured and tend to pop off. The valve cover gasket also leaks and pools oil into the plugwell, tho more often in #3 on the 2013+ MYs.

Good thing you don't have to ticket yourselves for going over the speed limit. The fine for that would be MASSIVE :nut:
