2006 pontiac g6 2.4L
girlfriends car started shaking really bad it also
wont go over 55mph it gives off a smell coming
out of the exhaust. it also has a loud noise coming
from the left side of the motor told it was the
timing chain smacking the cover. it just started
acting this way i will be replacing the crank shaft
sensor and both cam shaft sensors need some
help on why its doing if you need a video of the car
running i will email you
Sounds like you may have a clogged catatlic converter or muffler.
