Back after a long hiatus. I’ve got a 1994 XJ12 in storage which will start and move around under it’s own power. It will start quickly and idle OK, seems to be hitting on all cylinders (fast sometimes) and then when I drive it around the block it will work great for a few hundred yards, then start misfiring and will barely pull itself around. After it sits it will start up and idle again OK.
It’s been off the road for probably most of 5-10 years. I have an appointment in May to get it in to Champions Jaguar in Houston to get it road-worthy again. Should just go ahead and change plugs, wires, cap, rotor, coils, and fuel filters just as a matter of course before I take it in? I’m comfortable doing my own wrenching but not really into hard-core troubleshooting. I’m wanting to get the car to usable condition for a local weekend driver. This is my last Jag and I’m fine with spending 3-6K on it, and am willing to change more than I need to and not have to revisit similar problems over again.
