Idle rpm?

At what rpm does your 4.4 idle when warmed up - when stopped in P?
Mine is at 500(?)rpm - first notch on tach. Just curious as I was in a friends 4.4 and it seemed to be idling a little lower.

Mine is about 500-550 too. It seems a bit low to me but it's not rough at all...

Thanks Jay.
I love this forum - but I think it's turning me into a hypocondriac about my X. :rolleyes:

Anybody have to replace their wobble valve modulator?

Do you mean the modulator that controls the piston return spring?

It also depends on engine temp. If your engine is cold it will idle a little higher than normal...

No it drives the flux capacitor and regulates the space/time continuum!
