Turn the key, wait for a few seconds for warmup after it starts, then drive off.

There should be no need to depress the throttle with fuel injection. but it never hurt any of my cars.

I never even owned a car with fuel injection until 1985 (Lincoln Town Car) and even then I 'upgraded' from a 1946 Chevy Sedan!

Unless your neighbor can show you some factory literature that says not to depress the throttle during startup, don't worry about it.

My wife's ncle kept destroying the automatic transmissions in his trucks. We finally figured out that he KNEW you were supposed to shift them manually, that was the way they worked!

He'd go through two or three transmissions a year...so no one is really as good an authority as they'd like to think - not even me!
