Sometimes when im cruising at about 40-50 in 5th i get like a bucking feeling and the motor slams forward and backward.. yes it is light but it is irrirating... btw its only under partial throttle, as soon as i give it gas it goes away... i figured it was my motor mounts but i just fixed those... also btw i have platinum +4s cause i havent gotten around to getting the NGKs. Is it possible its the boschs or is it just cause of our 4.11 gears?
