Well, your car does have the electronic TB. It could be that motor that moves the TB.

thanks, ill look into it

looked into the etb and its on the wrong side of the engine for the sound i had the belt and water pullie replaced and the noise hasent ceased

Probably the power steering pump. Is it good on fluid?

Its got plenty of fluid, it only makes a noise when the gas is applied evin when driving in a strait line, i havent had any problems with the stearing,

Sabre might be on to something with the PS pump. They can make noise even when not turning and with little to no noticeable function change. (Fords do it coming new from the factory!) Water pumps could make noises like that as well (you said you replaced the water pulley?????) not sure what that means. I supposed the S/C could possibly make that noise too if the bearings are bad.

My PS pump makes a slight whining noise and it's fine. Has for years. Volume depends on temperature.

It does get quiet when it gets warm but its so loud that it makes me wonder if somethings wrong, ill have to get it swapped out to be shure

Mine had a slight whine from the PS pump too... had it for years too. Finally went out and am going to replace it before putting the engine back in.
