Check temperature sensor. I don't remember if your vehicle has two (one for the gauge, one for the computer) or a single unit that feeds both. If seperate (your parts house should know this) change the one that feeds info to the computer.
Essentially this sensor does the job of the choke on the carburetor on non-fuel injected vehicles, by allowing additional fuel into engine on cold-starts. After engine comes up to operating temp, it reverts back to normal run mode... (why you need to warm it up at excessive rpm before driving!) Good luck!

That is completely normal for your jeep product idol ranges it does this while warming up it should drop back to 800 when completely warm or when you put it in drive and everything is a go try using a better spark plug from AC DELCO lifetime warranty ones that'll keep some of the heat under control and abnormalities in your jeep product don't forget to change your timing belt at correct interval if not sure when that is call your local dealer and ask the service dept at how many miles should you bring in for timing belt change but of course you can change the belt your self with a little determination and knowledge.

The ignition timing is off.
The ECM (Elctronic Control Module) is responsible for that.
Take the Liberty to AutoZone to have them scan the PCM code (free) and ask for an explanation print-out (also free). You might want them to clear the error code afterwards, too (yes, free).
Let us know what the codes are and a summary of the print-out.
