Help diagnose nasty sound/rattle, 98 trans am, with sound link.
1. Car starts fine, purrs like a kitten.
2. Will hear a rattle sound as soon as I give it gas, more noticeable in lower rpms.
3. Super loud raspy rattle sound.
Watch "98 trans am nasty sound, rattle" on YouTube

The only solution is to turn off the car and turn it back on. It's a dice roll which of those 3 options will happen. If it starts quiet, the rattling will never come on. Starting the car dictates which option I get and will stay like that until I turn it off.
I will be taking it to the mechanic next week, but if any of you can shed some light on this mystery I would really appreciate it.

Although this may be very basic, have you checked the starter bendix / pinion to see if it is disengaging properly after the start cycle? The only reason that I mention is due to the randomness of the issue. Let us know when you figure it out.

Been hearing soundbytes of this and it's super similar. Might have hit it right on the head.

The truck starter uses 2 longer bolts instead of the 1 long, 1 short on the stock starter. It's not common but the small tab on the f body starter will break and take the outer starter bolt hole on the block out. Happened to me so I've recommended it to people so they don't have to deal with the headache. It's cheap insurance IMO. Any 2500 (6.0) truck starter will work.

Good to know, I never knew that. I'll probably be headed down that road before long, thanks for the heads up!
