Every now and then, won't idle
About a month ago, and now today, my wife's Grand Cherokee will start fine, but won't run unless she keeps her foot partially down on the gas pedal. After of few minutes of this, the car will return to normal. Both times the car was sitting for over 6 hours when the problem occurred. It is a 2000 GC with the 5.7 V8, 115,000 miles. Any issues or known problems that would cause this? Thanks in advance for your replies. Car runs fine other than this issue.

My guess is the FPR is letting the fuel pressure bleed off while sitting and not running. JMO

I just went through the same thing on mine. It ended up being the battery. Check my thread to see what I went through.
