00' wont stay running when cold
I have a 2000 jeep cherokee sport 4.0l ...with the current cold weather the jeep will turn over fine but wont stay idle and will imediatly stall out .... if i give it some gas it will fire up but only stay running when i have it idle'n over 1000rpms ....as soon as i let off the gas the jeep dies out and stalls ...Once the jeep is warmed up it doesnt do any of this at all and runs fine.... any ideas .....???

Instead of just pushing on them try unplugging them and spray some contact cleaner (Radio Shack) on them before reassembly. The addition of the cleaner and the physical unplugging/reattachment combo will help to make a better contact surface for the signal that the different components have to send to the ECU.
