The builder of my engine has set a minimum idle rpm to a little over 2000 when the car warms up, which usually takes about 10 minutes until it drops down to normal idle and is completely warmed up.
Until a few days ago I've had no problems with this, but lately I've been hearing more and more about how it's bad to let the car warm up by just idling and the better alternative is slowly driving it till it's warmed up.
So my question is would it be alright if I just let it warm up the way I have been, by letting it idle until the revs go down to normal like it has been tuned ? Or just start driving but at low rpm ?
Sorry if this is in the wrong section !
Thanks.
