Only refer to this customer complaint after a complete check using the XR25.NOTES
Erase the computer memory using G0** and carry out a road test.
Check there is fuel present
(fuel gauge faulty).
Check the fuel is of the correct type.
Check the hosesCheck no hoses are pinched
(especially after a removal operation).
Disconnect the pipe connecting the canister bleed solenoid valve
to the inlet manifold.
Plug the pipe to prevent an air leak.
If there is no other effect, the canister bleed is faulty.
