I just had this done. The car still hesitates to small degree during "parking lot" type driving. Anyone have the same reprogram issues?

My Fx35 does drop some RPM when I'm at red light and then they come up again. Annoys me....can't find the solution. Dealer doesn't know :bad:

Clean the throttle bodies thats the issue I had and it fixed it. There is a diy I made in the diy section

anyone had this issue? recently? I did the trans TSB update. only thing I have not done is spark plugs and throttle body clean

I did the trans TSB update and had the dealer clean the throttle bodies at the same time. The hesitation was there for a while but slowly happened less since only using Shell premium gas for a few months.
