Hi all.
This is the third day in a row that this is happening. When idling in neutral at an intersection, the engine will rev to 2000rpm for a few seconds and then go back to around 1000rpm. This will happen once during a drive.
Today, this happened three times, with the engine revving to 3000rpm at one occurrence. This seems to occur when the engine has not fully warmed up, yet it doesn't occur at start-up. It occurs only after about five minutes of driving.
Anybody have any idea as to what is going on?
Thanks.
