#1 of 3 Bought 99 Jaguar XJL by michaeljisom Nov 20, 2006 (10:46 pm)
I recently bought a jaguar that has mechanical issue from the prior owner running out of gas. The car starts and runs, stalls out at times and has this knocking noise that seems to be coming from underneath the hood (center of engine area). I got a great deal on it, but I am unsure of what could be the problem to fix it. Any advice on what this could be would be HIGHLY appreciated it.

Replying to: michaeljisom (Nov 20, 2006 10:46 pm) IF your car has an electric fuel pump submerged in the bottom of the gas tank and when the car ran out of fuel, AIR got to the pump, causing rapid deterioration of the pump- - The pump would not operate satisfactorly and send a reduced amount of fuel needed by the engine causing pre ignition due to a lean fuel mixture which leads to a hotter combustion temperature causing the knocking under the hood.

my wife gets motion sickness when she rides the XJ for rides over 10 minutes. Is it due to the air suspension. Is this anyone has any info on?
