View Full Version : 4.0 stumbles when warm starting?

My 00' XJ starts perfectly in the morning, and starts first crank pretty much every time. However, when I run it for a while, then shut it off for 10 minutes or so and then start it warm, the idle stumbles badly for about 30 seconds. It almost feels like the injectors are acting funny or something.

I searched for warm start and didn't come up with much, so I'm wondering if anyone else has had this problem, and if there's a remedy?

Search ''rough idle" , go to page four, click on "XJ misses out after restart with warm engine" or something like that , click on Sparkman's reply. It's a Chrysler service bulletin that should take care of your problem. Easy fix, wrap for the number 3 fuel injector which can suffer from vapor lock.
