When you start up your car cold do you hear a fan like motor start?It is located under the battery on the drivers side.It is called the air pump.There is a valve towards the back of the engine it is part of the air pump system.It is bolted onto a metal pipe it has a vaccum line going to it.The valve might ba bad as well.Some times the air pump gets water in it.Or the battery leaks acid and eats the motor.

i hear a loud noise when i turn on the heat or like you said at start..... i read around and looked on the net and ive gotten the same replay.. air pump and control valve.

now of course if i change that i will have to start the code right??? or ecu

Im not sure what you mean.If you replace any of those parts you will have to clear the codes.

No you have to purchase the Valve by itself.
