My 07 luxury pkg dts, has been off & on lately, hesitating while in drive at a stop idle. I've had it for a year or so & never experienced such irregularities, it only happen twice that I know of. The 1st time was ab 3-4 months ago, I had just filled up on premium 93 gasoline as usual, later drove off & had to come to a red light stop, the stop was on a slight hill incline, & I noticed the rpm gauge tweek lower then usual and I also felt it, but it went back to normal with a little gas applied while foot was still on brakes, more recently just a day or so ago, I was getting ready to leave out for the first time that day with a 1/4 tank this time, almost immediately after I put it in drive I noticed it again, then it went back to normal with a little gas being applied. No engine lights on or any other faulty lights showing the problem, but daily drive is still normal like nothing ever happen, so I'm ignoring it, but still curious to know what could be causing that little tweek as if it wants to cut off, any ideas as to where the problem is? 91, 450.
