Has anyone experience an idle drop? On regular running temp, the idle seems to drop a little below 700 rpm (500-600 rpm) then comes back to normal. This happens after coming to a stop. I have the 6spd manual transmission. I was told that this is normal on most 4 cyl cars. Thanks

Yes, this is normal. I have experienced it as well quite a few times especially right after a drastic temperature change. Its the ECU doing it's thing calibrating for AFR.

Here's a screen shot of my engine Idle specs after warm up. 660RPM is what it's at.
