I Do have a 2001 Jaguar s-type 4.0 and have had a lot of the same problems.for one coils and im looking into replacments Like the gms units.as for coil covers once i get me hands on an extra one to use I will be fabricating alum replacements.Thank you to all for the great tech insight and look forward to reading more.Most Jaguar owners have no clue as what is going on with there car.they just take them to the dealer.I myself cant deal with that.
