Hmmm
In my 06 GS, with the car stationary and in N, I've noticed that I can't hold rpm steady at 1500 to 2000 rpm or thereabouts. Periodically, every say 5 seconds, rpm will drop by as 200 to 500 rpm for a few seconds and then it bounces back up again. The higher the rpm, the steadier it gets. Over about 2500 rpm it's pretty stable. There is no obvious rpm fluctuation at idle, although I can often feel a mild brief roughness occurring periodically.
Just wondering if anyone else has noticed this. Maybe it's just an effect of O2 sensors feeding back and adjusting fuel trims?
Thanks.
