Went to go look at a '94 GSR 5spd completely stock today at a dealership. Took it for a drive and noticed it had a vibration at around 4,000rpm almost as if it was an exhaust shield or something like that. Sounded like it was coming from under the car but as the car got warmer, the noise would get quieter. One of the mechanics lifted it up and said it wasnt a shield cuz there was no shield installed on the car. He claimed it was just the way Integra's sound cuz they are imports and the air going thru the muffler blah blah blah = rice lol. But for all you VTEC experts maybe you know what the problem is and can tell me if he's hiding something from me and if it's something serious or not.
