cold start RPM

As soon as the engine starts from cold it immediately rips up to 1700-1800 rpm. Seems that the oil isn't given time to properly circulate and lube at first.... Won't this high rpm right off the bat potentially damage the engine?

in a word.......no, it will not harm the engine. the oil is pressurized as soon as the cranking starts, all bearings and surfaces are lubricated properly by the time the motor fires up. the high cold start idle is needed for various reasons.
What scott said. Also the fuel pump is activated when you turn the key 3/4 way. Next time, turn the key right before the notch which cranks the car and you will hear it.
LOL.

You can put your foot on the brake and press the accelerator pedal all the way to the floor and let the motor turn over for a couple of seconds on the starter. This will allow the oil pressure to build before firing off. Let off the accelerator pedal and car will fire up. This does NOT flood nor harm the engine...btw. I would recommend this starting procedure only if car has sat for more than one week or extreme cold conditions. FYI

Fuel injected equivalent to using a choke. Every fuel injected vehicle I have ever driven does this, why should a Mustang be an exception?
