A light cloud of white smoke is coming from exhaust. I just had the oil changed 4 days ago and had fuel injection cleaner added to a full tank of unleaded gas.

It could be doing its job, sounds like what you put in tank is problem. Oil change would not cause that. I would not worry unless it keeps going after fuels runs down.

The black plastic grille around the fog lamp can be removed without tools. If you look through the slats, you'll see 5 or 6 "clips" that can be GENTLY released with your finger. Once the grille is out (which is about 4 inches high by about 14 inches long), you'll see that the fog lamp assembly can be removed with 3 screws. Simpler than you probably thought!

SOURCE: white smoke coming from exhaust, smells like gas

Check the fuel pressure regulator. It should have a vacuum line attached to it - disconnect the vacuum line and turn the ignition on - if fuel come out then that's your problem. DON"T do this while the engine is hot or you could start a fire!

If the Service Engine Soon Light is on continuously there is a serious problem with one of the systems of your engine. Have it checked as soon as possible. Unfortunately, it could leave you stranded which will be very inconvenient.

Valve seals. When you shut the car off overnight, the oil leaks past the seals into the cylinders. When you start it, it burns that oil and smokes for a minute( actually it smoke all the time, just not as bad at startup).

White smoke coming from engine and exaust.

I'd have to see it in person. A small amount of coolant in the cylinders can make a big cloud of white smoke. So a head gasket or intake gasket could be leaking but yet be tough to find. If you start loosing coolant you'll know. Meanwhile I would probably not drive it very far from home for a few days/weeks.
Keep in mind, if it is very cold where you are, regular water in the exhaust is going to cause "fog" out the exhaust.

When I start my 2003 ES300 smoke comes out the exhaust

The same thing happened to my 2003 ES300 - the smoke is coming from the oil seeping into the motor's cylinders. This is the classic "Oil Gelling" problem in Toyota and Lexus vehicles. There is a factory recall on it, but it only covers to 2002 ES300 not 2003. The Lexus dealer confirmed my "oil gel" problem and went to bat for me with Lexus - they got the repair approved - Thank you Mr Local Lexus Dealer! The cost was nearly $4,000 - paid for by Lexus.

My 93 maxima got no power an smoke started to come out the tail end.

The best test is a compression test.
Blue smoke means it's burning oil, due to worn out piston rings.
White smoke means it's mixing antifreeze and oil due to a bad head gasket or cracked head or block.

I have a 1999 Mitsubshi Galant that blowes white/purple smoke after it has idled. Lets say at a stop light, or for the morning crank up. I am also having to add oil in between oil changes. Is there any...

If you're sure it's "smoke", then it's probably burning oil. But most likley it's water vapor. When an engine is first started and the air is cold, the water vapor in the exhaust will create visible steam. Automotible exhaust primarily consists of carbon dioxide and water vapor. If the engine and exhaust system are cold, the exhaust will be cooler when it comes out and it can create a cloud of water vapor.
However, if it's not water vapor, as I mentioned above, it could be oil smoke. If that's the case you need an engine rebuild since you probably have bad rings.

White smoke when pulling off fron idle

White smoke coming from the exhaust of a vehicle is almost always burning radiator fluid. Go in to a local shop and have them drain the oil and check it for any sign of water. If you are a DIY kind of person, drain the oil into a clear sided bucket and check to see if there is any separation in the fluid(oil is heavier so water will rise to the top).
If it so happens that you have water in your oil the most likely culprits are cracked cylinder heads, or a blown head gasket.
