Question about 2004 Jeep Grand Cherokee

04 Jeep will not idle

I have a 04 jeep grand and it sometimes will not start and when it does start it will not idle you have to feather the gas to keep it running. Also when you try and crank it all the gages will flicker to max position and return to normal position. Yesterday it cut off driving through a parking lot and this morning it started fine until i got to a store and it wouldn't crank back. After getting it started and reving to motor awhile I just let it go dead and it started back up with no problem and has been fine every since. Any help would be appreciated. Thanks!!

So many intermittent problems are caused by corroded battery connections, I would suggest starting there.
Losing/regaing contact can cause practically all of the symptoms you listed.

It can be caused by the battery terminals as well as corrosion at the starter (+ lead) or the negative not contacting well to the engine block or chassis.

For the battery terminals, buy a terminal brush at an auto parts store. These will have a female and male steel brush for the mating connector parts and maybe an additional straight steel brush to clean up the other ends.

Our GC seems to need love about once a year.

My 2004 jeep liberty sometimes doesnt wanna run I have to pump gas pedal to get it to run

Chrysler vehicles are infamous for losing there idle learn when battery voltage drops below a curtain range. And then has to be re learned by feathering the throttle. I would get the battery tested...or just replace it now that we're coming into winter.
It is possible you have a different problem such as an IAC (idle air control) or a MAP sensor (manifold absolute pressure sensor) But from experience I would start with a battery.

You could possibly have a bad EGR valve which would affect the vacuum which affects the idle. Check for a vacuum leak first then check the egr valve

Check engine light does not come on, no trouble codes. Idles rough and sometimes will start up and will die as soon as you let off the gas. If you feather the gas and get going problem will soon correct...

Yes, very much so!!! The fuel filter is often overlooked. They should be changed every 20,000 miles, or less. I would check the air filter also. I changed one last week, that didn't look that old, and the gas coming out of it looked like milk, I did another one on an other, and the gas coming out of that one looked like black ink.
