So I jumped another car with the Pathy today and at the exact time that negative cable touched the old car's engine block the Pathy's idle dropped a little and immediately I noticed rattle sound almost like a bolts in the muffler. MY theory is that the engine's idle dropped enough such that it shook the engine a bit and possibly loosened a heat shield or something.
Is this something that sounds possible? What could I look at to confirm this ? The sound happens with the wheels turned all the way to full lock or if the car is in Drive and stationary. Any other ideas ?
Strange Rattle after jump starting another car

sort of, if I stand on either passenger side of the truck I can hear the rattle pretty good. Drivability is fine, and the sound goes away after a while. I notice that when idliing the sound comes and goes as well. Maybe it is by pure coincidence that this happend during the jump ?ntech wrote:is it a rattle coming from the transmission area? (lay underneath and listen near the trans oil pan) If so, You may have put the trans into a perm. fail safe. I seen one not too long ago. Any lights on or driving problems?
This could be just a coincidence, but check the exhaust heat shields, where they are attached to the piping by steel tie-wraps (or whatever these things are called) - all of mine needed to be replaced within a few months of each other and all the rattles went away. There is not much other stuff that can rattle down there.
