I have a 2002 Civic SI and whenever Im in third gear usually going around 60km/h or so the steering column and gas pedal start to vibrate/shake..and then it stops ...it does it for about 1.5seconds. If anyone has any idea what this could be...any feedback towards this would be great! thanks guys!

 

well. it could be your tires aren't probarly inflated or are unbalanced. also the alignment could be off.
