What Rpm Am I Suppose To Be Idling At?

[Zebvance]

Just installed a digital tach because I didn't have a tach before and I want to see if I'm idling at the right rpms

If it isn't to low, the engine is bucking and idling rough, or to high then it's right. Every engine has it's own 'sweet spot' for idling and cruising. I've found around 600 rpm to be close enough for government work.

If yours is an 88 year model, then the idle speed is not adjustable. With that said, you will probably want to idle in the 750 rpm range. Idling too low, and you don't get as much oil pressure, and if you put it in gear with the lights on, A/C on etc... and it can stall out. But like I said, the computer controls it anyway, so I'm talking about the older versions when I say 750rpm. is ideal IMO

I believe factory spec is 750 RPM.

750 in D.
