I've noticed that, at times, my acceleration seems sluggish or impaired.
I have the 5-speed automatic, and, usually leave the performance setting in "S" mode.
The car is usually peppy and responsive, quite often revving up over 3-4 grand with a slight press on the pedal, and zipping along.
But, at times, the car seems to be being held back, and, unless I floor the pedal, it seems to be limiting itself to 2-2.5 grand.
This has happened at odd times, both when the engine is cold (blue light on, disallowing SI mode) and hot, but, it happens after I start the car and for the period of driving until I turn it off again, not during driving.
I have the 11,750 checkup next Saturday, so am going to mention this behavior, but, is this something known, or unique?
Thanks!
