erratic idle and black smoke
hi all, have been having a bit of trouble with the old girl lately. sometimes she will stall at red lights or stop signs. starts up ok with a bit of black smoke and seems to run ok till the next idle it will sometimes stall again or run rough. the fuel consumption is down a bit. this only happens now and again. any ideas on what to check. thanks.

First thoughts, as basics.
Clean the throttle body and throttle disc, "Jaguar Black Goo" will cause erratic idle and stalling.
Replace the Coolant Temp Sensor, the one with 2 wires for the ECU, as old age is against it now and maybe erratic signals to the ECU for fueling.
These both sorted my 3.2 a long time ago.

changed the coolant temp. sensor but seems the same.plugs have not been changed for some time so will do those on the weekend. if that is no good will look at taking the throttle body off for a clean. have not got a code reader yet, funds are very low at the moment, but will look into getting one soon. P.S. what make and number plugs are best for this model?

Anyone will work. Depends whether you want a simple one, a complicated one or one that can be read by your phone.
1. I have a u480 obd2 reader
2. I use Yhasi Movi Pro with my MacBook
3. I have OBD Fusion for my iPhone
You will need an ELM27 dongle for #2 and #3, make sure it's a Bluetooth dongle if you want to use an iPhone. The MacBook, I believe can use a WiFi dongle. They cost the same, but they don't work the same.

Champion RC12YC are the correct plugs for your engine. Don't bother with more expensive precious-metal types or multi-ground-electrode types.
I use a Bluetooth ELM327 and Torque Pro app with my Android phone. The ELM327 OBDII Bluetooth adapters can be purchased from eBay sellers for under USD $10.00, and the Torque Pro app is $5.00 from the google Play store.
My understanding from other members is that iPhones require a WiFi OBDII adapter (dongle). Vee, are you certain you are using a Bluetooth dongle with your iPhone?
Cheers,
Don

Jaguar subsequently revised the spark plug specification for both N/A and S/C engines to the hotter RC12YCC ("double copper") plug, which is no longer available, so today we use the RC12YC, which is identical in performance.
I'm attaching one of the TSBs that announced the change in specification to Jaguar spark plug part number EBC 8143, and a second TSB that reveals that Jaguar EBC 8143 is actually Champion RC12YCC.
Cheers,
Don
