I have a 2011 Roush supercharged Mustang. It is jerking while i am driving. If you hammer on it it still goes like hell but just when you are driving down the road it jerks a lot. Any ideas would be appreciated.

 

Drive on a different stretch of highway. There is a 15-20 mile section of asphalt on I75 north, I was jerking right and then left. After a few minutes I told my wife, "I can't drive worth a **** for some reason". After I got through the bad section, everything was good.

 

Sorry i should have been more specific. The engine feels like its jerking while driving. No engine light or anything. Feels like a miss but really goes when you hammer on it.

 

Has it always done that? Have you ever had it tuned? Could be as simple as your timing is too advanced. Any pinging (ball bearing in a tin can sound) when you are on light to moderate acceleration? Plugs could be worn.

 

If the situation is showing its *** under hard acceleration then I suspect you have a coil going south but hasn't gone bad long enough to throw a code yet.
