1989 xj40 Low Vacuum
Hi Again,
Following up on my last post with trying to solve the low engine Vacuum.
I removed the front spoiler to view the charcoal canister tracing all hoses . I found the purge valve had been disconnected from the connecting hose. The electric connection was still in place.
I removed and inspected all components and testing the purge valve I found it was faulty.
Having trouble locating another I carefully dismantled the one I had to find it was caked with dirt/dust/grime.
I rebuilt and moulded back together. Tested ok and reinstalled.
checked the jaguar manual for a schematic to make sure the installation was as it should have been.
Unfortunately this had no affect on my current Vacuum readings. I will keep looking.
Could some one assist with another issue.

- FAULT 23. The book reads Fuel supply as the description with in the Function column it reads " look for poor feed back control in rich direction" Sorry but I don't understand this.
- The other one is the elimination on the dash indicating a failed fuse in fuse location No 2. I checked all fuses and all ok. I removed the side cover making sure that there was no others fuses hidden away. ( as this vehicle was pre owned ).
