2000 XJR. pressing accelerator - nothing happens - ease off, re-press pedal, acceleration OK. Supercharger only works occasionally. Transmission problems starting to show - drive can suddenly stop but engine still revs fine. Move selector into neutral, back to drive, and off we go.
Now, restricted performance light coming on occasionally - goes out after a while. At idle, car is 'surging' slightly and turnover seems very unstable.
Are all these problems linked or indicative of very big bills ahead ? Transmission last checked about 8 months ago = no problem detected.
Any thoughts welcome !
If its a v8 its gonna be your throttle body its a complete assembly and is a common problem on these models

My mechanic said that the front cxygen sensors needed to be replaced on my 03.

The fuel filter is under the car, and above and to the left of the rear axle D
yes it sounds like a vacuum leak possibly the line going to the brake booster try to start the car open the hood and listen for a hissing noise you may be able to inpoint where the leak is and fix it with a new piece of hose or a fitting

If you get just a click you should first check battery charge and all battery connections. The click is probably the solenoid kicking in but without enough battery to turn over the engine.
