Wont stay on unless foot on gas?
Just did a full tune up (fuel filter seafoam plugs wires coils air filter oil) and randomly today I cannot start or keep my 3.8 running unless I have the gas pedal down. This is like 300 miles later. Car runs great it just seems as soon as I let off the TB its not getting air? I read somewhere it can be the battery? But the battery is fine. I have a new IAC as well. I checked out the TB and its clean. It was literally running a few hours ago!

What trim is your car? This could be a number of things. From a MAF sensor, clogged cat, etc.

04 SLE 3.8
Brand new cat to as well as o2. It is running great at idle i just cannot keep it on with holding the gas.
My battery is at 10 without cranking is that low?
Absolutely no CEL's. I would think EGR would give that?
Tried running it with MAF unplugged same. IAC is new. Only TPS remains.

Fixed! Brand New IAC was bad. Luckily had the old one in the trunk.

Thanks for reporting back.
It's a real shame that brand new parts seem to be defective more often today than in the past.

The parts store didn't manufacture the parts.
