The other day I was driving my car and accidentally downshifted into 2nd from 3rd at aobut 3500 rpms instead of 4th while applying gas. Hit the rev limiter real hard and the car didnt make a great sound. Then it smelled very bad for like 30 seconds and then i didnt notice anything untill the next red light. From a stand still, accelerating semi-slowly while easing off the clutch the car has a slight shake almost like the tires are slipping. THis only happens sometimes. I drove it a little today and could only make it do it three times.

OH YEA ANNNNDDDD.......... after having my car 5 MONTHS(since october 24th)... yes 5 MONTHS... I went to the gas station and guess what... my car did that stupid thing where you have to tilt the nozzle upside down to make the gas go in.

WHAT DO YOU THINK IS WRONG WITH MY CAR (about my downshifting icident)? Do you think i broke something?? What should I do?? Help!!
