Why does my Jaguar X300 make a noise when over run?
Used Jaguar X300’s – Common faults. Back Axle noise, especially on the over-run. Don’t be tempted to buy a car with any appreciable noise on the ‘back end’ You may have been told that the noise is due to a worn wheel bearing but this often not the case. Mostly, worn differential bearings are to blame.
Why is the air conditioning not working on my Jaguar X300?
Air Conditioning not working. By far the most common used X300 fault. The cause is often no more than a lack of use by the previous owner(s). As prescribed by Jaguar, the Air Con, should be turned on every 2 weeks or so to keep it maintained, Winter or Summer.
What was original resistance of Jaguar XJ6 engine?
The original sensor tested OK – with resistance of 1,250 ohms and inductance of 1 henry. However the replacement sensor seemed to cure the problem – almost! The engine would now rev to 3,000rpm – more than enough power to drive around. But it wasn’t right and still misfired.
What should fuel pressure be in Jaguar X300?
The fuel pressure gauge in the flexible pipe should show a steady 38psi with the engine running, this varies a little with inlet vacuum as the engine is revved up. Just for completeness – a rogue MAF (Mass Air Flow meter) can give idle dip and lumpiness and/or a hot restart issue.
