2008 Yaris - idles at a lower rpm

[SHI2RG]

Just flushed my automatic transmission.. Took off and cleaned the pan and replaced the screen filter. The car runs way smoother than before... Many thanks for all the help. :thumbup:

The other issue I am seeing is that the cars is idling at around 500 RPM when idle. Wonder what could be causing this to happen and what can be done to rev up the rpm to around 650, which I believe is the normal for Yaris.

As always thanks to all your time and help.

I am observing 2 issues here:
1.) Although on "Drive" the car rolls back when idling on a slight slope.
2.) The entire vehicle seems to shake at that RPM.

I personally believe that the idle RPM should be between 650-750.

BTW I did replace my Battery too with a CCA rating of 575, which I believe is higher than required. Could this be causing the problem?

My yaris had a rough idle almost to the point of stalling, it was a filthy throttle body
