What RPM at neutral grear we should have on 3.0CS automatic

[remydedez]

Hello everyone, the engine of my car runs at 1500 rpm when it is neutral I would like to know if it was normal? Once a speed is engaged, the minutes of turn go down between 800 and 1000 minutes. thanks ;-)

I think not. Between 800 and 1000 is normal.

Which year and model do you have?

 

[remydedez]

yes between 800 and 1000 when drive is engaged seems normal but 1500 rpm when shift is in neutral seems high no ? it's a 1973 3.0CSA but i changed the cylinder head

Check for vacuum leaks.

i saw this on this link so 1500rpm shoul be normal ?

That seems high if engine is warm. That image could be referencing cold start with choke

 

[remydedez]

maybe the choke has a problem...
