Sorry, but you're going to have to be a little more specific; 'heavy' is pretty non-descriptive.

When I start the car & it running it's very loud not really sure how else to explain .

Is it clattering, booming, rasping, groaning, whining, growling? Is the noise coming from under the hood, under the car, out the tailpipe?

I would say growling

Where is the noise coming from? Is it most noticeable inside or outside the car?

Depending on the temperature, the car runs at a fast idle when it is first started and after in warms a little it slows down to normal idle speed. Maybe this is what you're hearing.

Here's an Update , the noise was coming from the A/C compressor I had it replaced & now the car sounds great & is running well.
