I just recently purchased a 2003 Jaguar s-type and learning about it is a lot of research.I put all new coil packs and plugs and that really made a difference as the car was running terrible I found that 2 coil packs were not firing.The car is running smooth now, how ever the check engine light comes on after driving about 100 miles the code is coming up catalytic deffeciency .I just have to keep on it untill I get all the repairs that it may need.I will post pictures later.Thanks !
