RPM's at startup.
Last 3 days noticed when I started up in the morning the needle goes to one and sits there for a little bit then goes to 500 rpm's as soon as I go in reverse or any other gear. Then yesterday the needle went right to one , went up a tiny bit , down , up then to .500
sorry for a newbie question but that's what I am lol so is this normal ? "Dade Jeep Dodge " says it all depends on the temp.
usually the car just starts up and sinks to 500rpms... I guess but I don't alaways pay attention just theese last 3 days the startup seemed odd?
