Hey guys...so after cleaning injectors ( twice ), replacing the O-rings, plugs the rough morning idle persisted. Dealer repeated smoke test which now showed a problem with the EGR...that was replaced .....things got better for about 1 week and now rough idle came back...No lights or codes ...nothin...dealer is stumped....Could the cold temp sensor be the problem since the problem only occurs when the car sits 7-8 hours or more....crank sensor was ok...????? There are no performance issues of any kind....????

 

If the Jaguar dealer can't repair it after 3 tries, tell them you want a replacement car!!

 

I am working on it right now with a lawyer....The car has actually been in 4 times for the same problem...The weird thing is...I actually still love the car...it's just been a lot more hasle than i thought it would be...
