Well i have an engine lite on already and it's been on for long time. I bought this car march 2014 in la. when i tried to register DMV wouldn't let me. It seems the car was bought from carmax auction by exporter. Car was suppose to be taken to mexico and could not be registered in states. Car had this problem then. Car sat for 2 years. I bought cheap car. Cheap car wont pass smog. Re-enter Jag. Got jag registered now this problem is interfering with my bliss

Ok since the light is on this may or may not be related to the issue. It could be a cylinder missfire from a failing ignition coil. I recommend we go to your local parts store to see if they have an OBD II scan tool we can use to retrieve the fault codes. They will be a P followed by four digits. Let me know.

Hi again
I took my Jaguar from Fresno to Sacramento yesterday and so I have better info on my studering problem. While on freeway I had to pull over to check my tires. When I tried to get up to speed I had to step on gas hard. Jag would not pick up speed. Just studdered. I was just over 35mph so I used cruise control button to bring car up to speed to pull back into traffic. It worked beautifully. What ever is going on would seem to have something to do with the cruise control. Again after using cruise control car has no problem excellerating once cruise control is turned off for period of time. Period of time seems to be random. At lower speeds stepping on gas pedal hard will cause Jag to spudder and always just before 3000rpm
