so i fixed my front axle shaft yesterday. went to start the jeep and drive home from my shop and it will start just fine but it will only run for about 7 to 15 seconds and dies starts right back up and does the same thing.. any ideas what it could be? a shop said maybe the idle stepper motor.. or a dirty throttle body any help would be great since im driving my tuff truck now and its not exactly super street legal!!
starts but wont stay running

What year XJ? You can spray some oil into the IAC orifice while the motor is running. This usually loosens them back up. If it's a Renix (Pre 91) remove the IAC and clean the pintle and seat, let a few drops of oil run behind the pintle (piston). They get pretty gummed up. After 90 they usually just need a few squirts of spray oil. I avoid heavy use of solvents on the IAC, because the pintle rod is lubed from the manufacturer and solvents may wash the grease out.
Don't try to move the pintle (piston) by hand, this can damage the rod and tiny drive gears.
There are other reasons for the motor to die after a few seconds. Depending on the year the list of probabilities changes some.
