This 2010 3.8 currently has about 43,000 miles on it. It has the stock tune, cbe and k@n drop in filter. If i take off and accelerate hard through the gears, there is no problem. If i an cruising on the highway at 65-75+ mph and keeping a constant speed.....once again all is good.
...However, a lot of the time if i gently come in to the throttle from say highway speed, i can feel a ever so slight hesitation, or if i am " babying it" while shifting up through the gears...once again, a very slight hesitation. Not always, but enough. I'm thinking its because the car is set so rich from the factory? Its not smoking and is getting great gas mileage. I am planning on getting a dyno tune soon which hopefully will eliminate this? Its not bad enough to consider it a plug or fuel filter problem. When it does happen...the engine is still running smoothly. I did a search but could not find a good answer.
