alright so last nite me and some friends were driving around.no particularly hard driving or anything and i was smelling something burning.at first i thout it was something outside but then it didnt go away.i didnt really think anything of it bc my temp guage wasnt high or anything.when we stopped i popped the hood and could see the smoke coming out.it was a burning rubber smell coming from the intake manifold side of the engine but it was dark and i couldnt see anything.then this morning i started it in front of my house.let it warm up,drove it around the block,came back and it was doing it again.all my fluids are good and none r getting too hot.i looked down the side of the engine and couldnt see anything.the car doesnt run any different and im baffled.any thoughts?
