ok well it only happens wen im just accelerating slowly/ regular... wen it happens....if step on da gas more or let go of the gas pedal fully it stops.....i feel it on da pedals....a lil bit on the steering wheel...but it seems to me like the whole car is vibrating....almost like lil fast hops only 34-41 mphs.....it also seems to me that all the tires and rims are good...ima try rotating the tires if u think its a rim or tire buteverything else is in tack imo....but who am i to say that?????? wat do u think it really is???
