Read code and it states a knock sensor issue. The car when accelerating
sometime just doesnt respond and seemes very sluggish. After a little
while it seems to kick in and i am off an runing. Want to know i anyone
has had this experience and if replacing the knock sensor makes sense ...

Need a dog guard to keep an obnoxious Jack Russell in the back.  Is the
dealer's unit worth 150?  Are the aftermarket units (like from Petsmart)
good enough?  I don't like having to go through the ceiling...
Thanks
