Default Idle speed 99 six speed
What should the idle speed be on my 99 6 speed? (How) can it be raised or lowered?

Idle speed on my 98 6 speed is 750 rpm. You will need tuning software to change it.

Correction, my idle speed is 700 rpm.

Very simple to adjust with HP Tuners not that you should need to on a stock car.
My idle speed is set at 800 not sure if it was tuned before I got it but thats what it was at when I got it.

Mine is a '98 six speed, but I'm not sure why they'd be different...Somewhere between 700 and 750, and 900ish when cold
