New Problem:
Hey guys, my dad's had his Mazdaspeed since november and this is the first problem we are having. One day i took a buddy out to show him the car, i tested it out but didnt NAIL on the car, i floored it about 2-3 times and then just drove along and showed him the features. Anyways i got home and precided to drive the car up the driveway, now my driveway is probably a 30 degree angle and a b**** to get up, after i got up i noticed a raw fish smell and i knew i had burnt the clutch coming up the driveway. Anyways that monday on the way to work the car started to shake back and forth in everygear from 2500-3750rpms. The shaking is like when you go through a playground zone in a standard in 2nd gear and give it gas how it bounces around and whatnot, thats what the car feels like.
Well i took the car to the dealership and they analyzed it and all they could come up with was bad gas.. i told my dad it was bulls*** and that it was something driveline related. Anyways, its been about 2-3 weeks and lots 2-3 fill ups later and the problem is still here.
Anyone got any ideas on what it is?
