Hesitation when lighty pressing on gas only down hill

[wagner73]

I have a 2005 G35 50 k miles sedan. When I press lightly on the gas anytime going down hill and some times on flat roads around 2500 RPMS and above there is a hesitation like if you were missing. you will not notice this driving normally and accelerating fast. This only happens when very lightly pressing on the gas going down hill. It is hard to make this happen. a example would be a maintenance throttle. I brought my car to the infinity dealer and the checked it on the computer and found nothing. They changed a valve in the transmission and I had the transmission flushed. They changed the valve in the transmission because it seemed to be the same problem my brother had with his 2006 g35x sedan which had a recall to change the valve in the transmission. after they did the work the problem was still there. I felt like I was able to do the same thing in the 2009 g37x sedan loner car that they gave me. Remember you have to lightly press on the gas going down a hill around 2500 RPMS and above. The are no modifications to this car. Thanks please help.

If it happens on all models you have driven then I simply would not worry about it. The ECU/TCM can do strange things at times.

I would be interested if it happens when you drive yours. If you get a chance just try it, I would really appreciate it. Thanks for your Time.
