Let me have your beater turbo hehe

 

Sounds normal to me. Unless you have cams you'll have a semi jumpy idle. However, those numbers sound normal.

 

To all you ~500rpm idlers, take a close look at your tach. Between 0-1000 rpm, the 500 mark is pushing against the 0. The midpoint between 0-1000 is actually about 750rpm.

 

I have the same idle RPM..

BTW, when your car gets warmed up, and idles, does the cabin vibrate like crazy at the 700rpm idle?

Mine does, however, once i push the throttle a bit to 1.5k range, the vibration goes away..

 

my display meter reads 1400rpm cold @ 88F water temp. 550-750rpm warm @ 160F water temp. In traffic with IA Temps reaching 110F I'll see 550-800rpm @ 190-205F water temp.

Sounds normal to me.
