flooding
I was told by 3 people to rev up my engine to 3rpm every time before you turn the engine off to prevent flooding. Is that true? Cause it does seem like it, cause when I do it the car starts up better.

How have you managed not to come across the answer to this in your 4 months here so far?
Your engine needs to be warmed up before turning it off. If you're in a hurry, revving to 3k for ~10s can help to get the temp needle moving up more quickly. Taking it around the block would be better.

Here is a bit of background on the whole flooding issue.

Flooding is only a concern if you have a weak ignition system. The problem is, your ignition system usually fails very slowly, so it is a gradual decline. The alert and responsible owner will detect the drop in mileage, the drop in power, the rougher idle, the occasional misfire, and replace their coils, plugs, and wires before it gets bad enough where there is a chance at flooding.
Every single flood I have seen reported for the past year or so ended up coming down to a failing or failed coil or spark plug or spark plug wire. But by then, they also generally have a fried cat that needs to get replaced as well, and possibly an O2 sensor or two. Stay on top of the maintenance (long term included!) and you will wonder what all the fuss was about. Coils ($160 for all 4, 20 minute swap), plugs ($80 for all 4, 10 minute swap), and wires ($50-140, depending on quality, 2 minute swap), should be replaced every 30,000 miles, possibly sooner if you detect something starting to fail, since people have had them fail as early as 8,000 miles or 15,000 miles, though that's rare.
You don't want to shut off while it's cold simply because when the engine is cold, the ECU dumps more fuel into engine to help it warm up, and it leans back once the engine is warm. This extra fuel can make it harder to start an ignition, which a healthy ignition system is perfectly capable of overcoming. Weaken the ignition with failing plugs, coils, wires, alternator, or battery, and you have a flood on your hands, and all the associated problems from that.
