Dont know if anyone else has had this problem, and it just started happening to me.....but when i am getting ready to go to work and go outside to start my car and warm i up, when i start it, its making a strange bogging sound and the whole car shakes.....after about 3 mins it stops but then the idle goes kinda high close to 3000rpm after it warms its ok, and the rpm drops, but this is starting to worry me, can some one please help?

 

i dont know if i have the same problem, but in the morning as well, when I start up my car, it makes this weird vaccum suckin noise of some sort, i dont know how to describe it, and also when i shift gears, it shifts kinda hard and jerks.....dont know why, but only in the morning.

 

i dunno about the shaking but the f'ed up idle could be your afm (air flow meter), ps dont quote me im just guessing but it's possible
