Weird things happening?

[Dbese]

02 EB 4.8L. Every once in awhile when first putting into reverse, car idles all weird. It gives this sort of sound like its almost dying but doesn't. What do you think is causing it? Also leaking coolant by about the gallon every couple weeks, not seeing a lot of smoke from the tailpipe. Thinking intake manifold, anybody else? Last but not least, when going over bumps, speed bumps etc. I get a faint kind of screeching sound, as if you were walking over an old bridge. Anyone know what might be going wrong there? Ball joints, control arms, etc? Thanks a bunch. Just trying to nail some loose ends here on the ole Ex!

Sounds like a dirty iac clean the TB and maf sensor,

Coolant leak could be the thermostat housing, they are a pos mine leaks too,

Squeak could be ball joints and sway bar bushings,
Get a grease gun and needle and grease the ball joints, just poke it into the rubber dust boot. For the sway bar you can try to grease it, or swap in some urethane bushings
