Default Code P1179

95 4.0 Coupe
Check engine light came on this morning on my way in for an MRI on my neck. Went home and read code and took our Explorer to work. The car seemed to run rough and stalled 3 or 4 times this past week. I thought I would change the plugs and check the coils, but that was before the light came on. I need to find out what needs to be cleaned or replaced over this coming weekend. So the question is, where do I start. I am still going to change plugs and have a look at the coils and related wiring. What should the coils ohm out at and is that a valid test?

P1179 is a long term rich fuelling code, not an ignition issue. It should take just 30 seconds to google it and find the Jaguar bulletin detailing the approach to try and pin down the fault.

Good luck
