Hi Edgar. Thanks for contacting us today. Honestly, there are probably multiple problems with your Jaguar S-Type that are leading to all these symptoms. Some of the common reasons why an engine would stumble, or cut off while driving or slowing down include damaged mass air flow sensors, EGR valve or a throttle body that is damaged. This is quite common with early 2000 Jaguar models. This could also be due to ignition system component failure, such as spark plug wires, coils, or spark plugs that are worn out as well. Since there are so many possible sources, including the source of the engine ticking and smoke, it’s probably best to have a professional mechanic inspect your vehicle to determine what needs to be repaired or replaced.
