I drive a '91 vert. (NA). seems to run fine, I don't have extra money to replace all of my suspected parts so i'm asking you for advice.


just for background info: Tranny will need rebuild shortly, RB headers to single stock muffler (it sucks, I know. I had to pull my old exhaust off.) 125K miles on engine.

when in transition from first to second, a wobbling noise comes from under my hood. sounds like it is coming from the air pump, or one of the corresponding belts. I replaced all of my belts last week, so i don't think its them.

There is also a lot of white noise coming from the engine bay during acceleration.

Any help would be appreciated.

you're gonna need to do better than "wobbling"...engine mounts? alternator/ air pump bearings? tranny mounts? ACV/ silencer? the list goes on and on...

 

air pump bearings sounds close. I'll check that out.
