See if you can get someone to help you find the source of the noise.
I've seen muffler hangers shift and open small holes, also seen
manifolds go bad. The catalyst if bad tends to rattle and cause crappy
emissions. Changing exhaust parts is one of the least technical jobs
on a vehicle. It is also one of the most painful in terms of stripped
bolts, busted knuckles, etc. The hummmm sound could be an exhaust leak
or a muffler with a broken internal baffle. A good local mom and pop
muffler shop might be willing to check your exhaust system for a few
bucks. The name brand chains tend to be about the same price as a
dealer and not as good.

1. How hot should the engine be on a normal driving? looking for
temperature here.

2. Where is the ac evaporator on a 1995 jeep grand cherokee, my ac has
that
dead mouse smell. gonna do the lysol thing and that.

3. Should i do a cooling system flush, maybe the engine is not properly
cool thereby
causing it to over heat and clank

thanks

1. How hot should the engine be on a normal driving? looking for a
temperature here.

2. Where is the ac evaporator on a 1995 jeep grand cherokee, my ac has
that
dead mouse smell. gonna do the lysol thing and that.

3. Should i do a cooling system flush, maybe the engine is not properly
cool thereby
causing it to over heat and clank.

thanks
