Hey does anyone know what consists of the major 90K mile service that supposed to be done to these XJ6's? I've come across it mentioned before as well as people who are selling them. Mine has 94K and I replaced the thermistat, thermistor sensor, and had the coolant/radiaitor all flushed out, etc. Anything else I might be missing that would make a major difference in how in performs or to prevent problems? Thanks!!

 

Alright sounds good. If I dont end up selling it this spring the new spark plugs were on the to-do list. Then I'll end up doing the fuel filter too. Thanks again!
