Ok for about 2 months now, when i start the car up and start driving, soon as it hits 1400 rpm's is rattles realllllly loud but only at 1400 rpm's soon as i go over that it stops, and under it, it stops as well.. also, it only does this when i start up, after like a minute of driving, it doesnt do it anymore... but its so *** damn embarassing, everytime i start my car and start driving, it just rattles in the engine or something realllly loud and everyone can hear it, it embarrasses me when i take girls for a ride... speicaly when im driving real slow and it hits 1400 for like 3 seconds it just rattles really loud... what the hell is this, im too cheap to go get it fixed, please help.. thanks

 

could be a heat shield or something. start the car cold, have someone get it to make the noise and look for it.

i'd suspect a loose exhaust pipe, heat shield or shrould. take a look around and see if you can find anything loose or a shiney spot on the metal where it rubs.

yeah sounds like loose exhaust, have someone keep it at 1400 and go look around your car for the rattle. when the engine hits 1400,,,it probably produces a vibration note that rattles something only at that "frequency". sort of like hearing things rattle when a subwoofer hits a certian frequency, but then when it moves out of the frequency it stops rattling. after the exhaust pipes expand from the heat, they might get tighter and not rattle anymore, causing what your describing.

just my guess
