Maybe im parranoid, but for awhile Ive noticed when my foot is on the gas when im in drive (auto ) it will shake a little bit, not alot but noticeable. I was thinking its just from the engine? but I wasnt sure. didnt do this when i first got it.

also just to post it, sometimes when im drivin the auto, when the ecu shifts. its only happened maybe twice. but I can hear a clank from the engine bay...i dunno.

Oh yeah, when u guys w exhausts turn your car on, if u rev ur engine up to maybe 4k or higher do u get a little tiny bit of puttering that lasts for maybe a split second?

Maybe someone could shed some light, plus im at work and bored and just started thinking.
