Problem with my 01 GT ? some help

DEFIANT · January 19th, 2011, 11:28 PM

Hey yall I was driving my car today and I came to a complete stop and I heard a low humming noise. Can't pinpoint where its coming from exactly but it does it when its on idle. I poped the hood but nothing, I only hear it more when inside the car. Any Ideas ?

BA98GT · January 19th, 2011, 11:29 PM

Auto or manual

Silencer on ur iac??

could be the alternator, do you have the stock Plenum if not could also be that

DEFIANT · January 19th, 2011, 11:57 PM

I did a search on the IAC someone had problems with but the humming I hear is very low and the video the MM member posted did not match my problem I have, the noise is different. Idk sometimes I feel like throwing my stang in a lake. I'm just asking for other ideas see if I can come closer to the problem.

Yea same stock alternator since 2001 baby. I keep my engine bone stock just a nice C.A.I.

Hit your IAC once or twice with a mallet. Ive heard when those things are going out, they hum really loud. Thats what yours sounds like since the symptoms are at idle.

lol yea I was reading the other thread. I read this and decided to give it a shot tommorow when the sun is up. But I keep thinking its something bad like the Transmission or maybe internal engine parts.

Shaun03GT · January 20th, 2011, 12:45 AM

I dont think so, I think its the IAC man

Scott2001GT · January 20th, 2011, 12:46 AM

yeah agree with the IAC. Since I have been on here I have heard that a few times now. It's a worth a try

Everett · January 20th, 2011, 12:56 AM

could it be the fan from your heater or a/c....try shutting that right off and see if it persists

DEFIANT · January 20th, 2011, 01:11 AM

okay cool thanks a million for the feedback guys. Now i have an idea on what to look for tommorow. Ill be fixing it myself once I find out whats going on. Ill update on it once i find the problem.

yup....n if that works its a free fix.....even better

DEFIANT · January 20th, 2011, 01:17 PM

So this morning I drove the car and then I noticed it humms when I press the brakes, turn on my a/c or when I put up both Windows. It seems like its starving for power. My RPM also drops a bit then picks up again. Is it the alternator?

eddy21x · January 20th, 2011, 01:24 PM

Could be thats why i mentioned the alternator seen it happen a couple times, go get it tested at autozone and advance autoparts
its free

Hotshot_98GT · January 20th, 2011, 02:12 PM

it's the alternator! mine did the same thing about 2 months ago. Honestly, even though AutoZone and Advance has lifetime warrantys on their stuff, me and my dad both are already having problems with our new alternators. I would suggest getting an estimate on getting your stock one rebuilt if theres an alternator shop around you

DEFIANT · January 20th, 2011, 02:27 PM

Anything else that could be causing the humming noise ?

eddy21x · January 20th, 2011, 02:44 PM

yeah your speakers but the alternator would do that though it would send a humm through your speakers thats a sign of it going bad, go get it checked out man

DEFIANT · January 20th, 2011, 04:55 PM

^^ lol sounds funny i think the car is singing at me through the speakers. Anyway im going to replace the alternator either way because ive had it since I bought the car new in Feb 2001.
