Hi all. I'm a new owner of a 2000 XJ, 4.0l with 45k miles on it. The Jeep runs great except at idle. I've replace the plugs and air filter but it still has this irregular skip at idle (the tach bounces around). Can't really tell if it's happening at higher speed. My dealer did a diagnostic check and said that the ignition timing was off a few degrees. He made a slight adjustment (no effect that I can tell) but also claimed that this engine has a "natural lope" due to factory specs that make it environmentally acceptable. Don't think that I buy that explanation. Every other vehicle that I've owned (including the 91 Explorer w/220k miles on it that I sold to buy this Jeep) ran smoothly or had an identifiable malfunction.
Is this really something that I am supposed to get used to or might there be a correctable problem here? I have no clue about what may or may not have been done, maintenance-wise in its first 40k miles. Would dirty injectors be a likely suspect? Thanks for any suggestions.
