Need CSS Help

Hello:

My site is cngcarz.com

I used this code to modify my header nav bar:

/* Start restyle the main menu */
/*CHANGE */
#access {
margin:0;
padding: 0;
clear:both;
height:51px;
background: #d6eaf8 url(images/menubg.gif) repeat-x left top;
}

#access a {
color: #bbb;
line-height:48px;
margin:0;
padding:0 15px;
font-size: 9.4px;
text-transform: uppercase;
text-align:center;
}

#access li:hover > a
{
color: #333;
background: url(images/menu-bg-hover.gif) repeat-x left top;
}

#access li {
background: url(images/separator.gif) no-repeat right center;
}

#access ul ul a {
border-bottom: 1px solid #555;
}

#access ul ul :hover > a {
background: #353535 url(images/dropdown-list-bg.gif) repeat-x left top;
border-right: 1px solid #000;
border-bottom: 1px solid #000;
border-left: 1px solid #000;
}
/* End restyle the main menu */

I since decided that I didnt want that in my CSS so I removed it from the style.css file but the nav is still there reflecting these css changes?

Also when I go to the webpage right click, view source , and then look at the CSSS this piece of code is still there ..what can I do to fix this issue? and remove this from my css ?

Thanks!
