Weird sound and shaking...

[SexySixer707]

There is a wierd humming sound when I'm in neutral stopped. And the Stick vibrates as well. Not real bad, but noticialble when you listen. When I press on the gas it goes away, then a second after I stop it cmes back. It does'nt sound like it's coming from the engine bay. What could it be?

The fuel pump?

[SexySixer707]

Not sure what it is. It vibrates on the passenger side though. It's like something is rotating underthere. Dammit!!!! Hope I don't have to spend money repairing. That will leave me nothing to upgrade.

Hrm, doesn't the cat have a hanger off the trans? Or it might just be a heat shield coming loose.

[SexySixer707]

You know what I did do the spark plugs last weak and had to take off the heat shields. Could it be that? It may be loose. Ill check.

Jack it up, let it run and look what is doing. Then go from there.

I was actually thinking of a loose heat shield on the cat, but it could be your manifold shields too.

flywheel?

[camaroman1181]

yeah.. sounds like it could be an exhaust problem to me.. i have a small rattling noise at idle too thats caused by the exhaust pipe vibrating off the cross member... i hit a raccoon and it bent the crossmember up a bit. in your case it could also very well be a heat shield. maybe crawl underneight there and see if the exhaust is touching anything first, then check it out when its making the noise and see if you can narrow it down a bit...

Theres no Heatshield over the cat. It's not evern a cat. The guy put a bullet muffler in it's place. I did the night b4 slam on the breaks cus I almost rear ended someone. So I slammed on it. I do almost hit the bottom when on the freeway when I hit a dip. Need new shocks too. I hate the bumpy ride.
