First check for vacuum leaks, rubber vacuum lines can dry out and crack especially after sitting for a while

SOURCE: jaguar s-type 2000 V6, car stops

I had the same problem it would run good in the freeway but if I slowed down it would turn off. If I was driving in the city same thing good until I hit a light. I took it to a mechanic and it had a leak. One of the boots close to the firewall was split open and was observing air. He told me that the only place it should be absorbing air thru is thru the air filter.

Your exhaust has four 02 sensors. Code PO154 refers to no activity at bank two, sensor one.,Typically 02 sensors are good for up to 100K miles, after that their performance declines. You can try removing the sensor and shake it closely, next to your ear ( listen for a rattle). If you hear a noise while you are shaking it. The 02 sensor is junk. The side that Cylinder #1 is on is "Bank one" the other side is "Bank Two". Sensor one refers to the upstream senor (the sensor located before the CAT. Sensor Two would refer to the "Down Stream" sensor. Which refers to the 02 sensor located after the CAT. I hope that helps. Please write back if you have more details or questions. Good luck.

Engine shaking making a rattling sound

You may have a broken engine mount, but without actually seeing the car it is hard to say for certain. But a broken engine mount would cause your engine to shake and possibly a rattle. I hope this helps you out. If you have any other questions please feel free to ask.

go to checker and have them run the code for check engine light. it will probably come up as a lean code bank 1 or/and bank 2. on my x-type it was an o-ring in the intake that was cracked mechanic found it with by spraying carb and choke cleaner around the intake components.the shaking.... if it occurs at higher rpms is your car being in limp home mode i think about 3000 rpms will go away when intake problems are solved. car cutting off ? take it jag maybe a weak fuel pump,clogged jet pump or clogged fuel filter just did all of the above to my 02 x-type 3.0 sport w/ 75,000 miles.
