Hopefully I am posting this right guys. First time on a forum.

I just purchased a 2005 g35 coupe. It has 65000 km on the car and she's a beauty. Loving it.

The only mod is an aftermarket intake.

When i accelerate and let the rpms drop when i shift gears i get this fluttering / shakey / slight fluctuation / bouce/ not sure how to describe, on my tachometer/ RPM gauge.

Here is a link to a video in slow motion

You can barely see it until the last couple thousand RPMs but it is constant accelerating and decellerating .Much more noticeable in person. Any expertise and knowledge is welcome and appreciated.

 

Perform all 3 of these relearn's for the car, ECU, Throttle position, Idle air volume. Use a stopwatch or something else that has accurate seconds, the timing is VERY important.
