annoying clicking noise
 

I know it's got to be a coincidence but after i rotated my tires i have a clicking noise when i press or let got of acceleration pedal fast. it's a one time click and then it's ok. but when i press it or let it go fast again it makes that clicking noise again. From the drivers side it sounds like it's around the pedals. but i'm not sure any more. Any1 has any ideas?? thanks
