My 2000 year S type 3 litre has just 48k on the clock absolutely immaculate and a joy to drive until recently
Car would cut out out when driving but restart immediately ,drive for a bit then do it again
It had a kind of jerky acceleration as well I would floor it and it would think about things then kickdown
Have had a new fuel filter a faulty coil pack changed and also replaced the cats in case they were damaged
Eng man light flickered now and again as well Fault code reader pointed to the Throttle position sensor which as you know is not a part you can buy new anymore but I got a throttle body
and sensor from a breaker.Car started no problem went for a drive and then it just cut out again and wouldnt re start this time.
Other forums point to possible breather pipe problems or air leaks from somewhere.
I really want to keep this car on the road as I love it
Any help appreciated also do you think there would be any use it getting a Jaguar main dealer to see it
Cheers
