I appreciate all the help, guys. I have a few little problems with my stang (a '98 GT) and I was wondering if you could help me out a little with it. I plan on taking it in to have it looked at, but I'd like to have a general idea what I should and shouldn't expect to pay for.

Here they are:

a.) After shutoff, the car hisses...sounds like a pronounced drip onto something hot, maybe the block or intake manifold, yet when I open the hood and I can't see anything. Doesn't smell like coolant, yet when I'm parked on even the slightest hill, I get the low coolant light until I drive onto a flat road.

b.) Fuel gauge goes nucking futs. I'll look down and it'll say 1/2 tank. 2 minutes later it says 1/4 tank and I'm like wtf!? THen it'll go back to half and so forth. Is it just a float that needs to be replaced?

c.) I described in an earlier post. Suspension makes a weird hissing noise. I don't know enough to tell if it's a spring isolator rubbing or leaky shocks/struts. It's factory 98 equipment. Also, when I get on the brakes hard, you can hear either the struts or the springs (again, can't tell) compress.

Thanks again, guys!

 

a: most likely AC condensation dripping on your exhaust - its just water thats why you don't smell anything
b: I've heard alot lately about sulfer content in gasoline getting bad and causeing that very same problem, check into it
c: springs won't make a hissing sound, shocks could. springs could make a squeeking sound though. the easiest way to check shocks is to bounce the car on the corner of the shock you want to check - and see if it takes more than an up and down motion to level out. you can also have a friend do that while you listen to see if its making more noise than the rest of them.

Well this is what I can come up with, maybe try these out and if you still can't get it figured out someone else can help.

 

A.i have the same prob. with my 99 cobra its not the a/c sound like a soliod buzzing sound for a coulpe of seconds,,,also when i shut my car off i hear a buzz sound from behind the speedo area,,they may be the same thing not sure dont drive it alot..when i hear the noise everything is turned off so its not the a/c/ dose this so like what your car is doing ????before you get out of car car to see what it is ,it stops making the sound??[:@]
