2007 Kia Carens [ARCHIVE]

I've noticed this too, although I don't seem to have an explanation on why it happens. All I know is it doesn't seem to have any problem with the engine or performance of the car altogether. Parang bumababa lang siya sa idle at a certain speed or gear.

I might be too simplistic for me to say it helps save gas. I'm not too technical about it pero it could be an engine management thing...

I've been traveling to Bicol Region. And, these are my observations:

1. The speed would gradually increase to 100 kph or more at the constant 2,000 RPM.

2. If I revved it to overtake, the RPM would reach 3,000 RPM then suddenly drops to 2,000 RPM upon reaching 90 to 100 kph. So, at much as possible, I maintain my speed at 90 to 100 kph.
