Ok...i've noticed something about my car or maybe its just me. Anyway is this normal? some days when i turn on the ignition it will be loud and other days it will be kinda soft. Then the drive is somewhat different other days too. some days it will be loud, fast, and responsive. Other days it will be sorta quiet and kinda sluggish at times...well not really sluggish...just not too fast. do u other guys seem to have this? or is it just me

 

Did you have your windows down when it was louder ?
