Acceleration Surge After about 5 mins

alfiecat · 01-26-2013, 11:11 AM

Hi Guys,

I've been driving my 370Z now for just over a month and something strange happens every day after about 5-10 mins of driving. I'ts not a problem, I would just like to understand what is happening.

I'll be driving for example about 30 MPH in 4th at a steady speed and then I'll experience a very slight increase in revs (slight acceleration) and then it settles. It lasts for about a second or two. A passenger wouldn't notice it but I feel it every day.

I've read a little about the open and closed loop feedback control for the throttle. Is this the point where closed loop takes over and there is a slight overshoot of the control system?

I did try and search the forums, but to be honest, its quite difficult to describe.

Regards
