Help Needed - Air Flow issues - is this the fix
Mu XKR 2010 model have an issue when warm (100 km +) - it will not accellerate as it normally will
I have change air flow meters - I have had technical assist from Jag
We have tried to find any
Now my new mechanics suggest these vacuum "pumps" sound bad (noisy) and suggest I change them - see picture
Thanks in advance

From the workshop manual, possible causes for that code are:
Test procedure to carry out:
Sorry, I've never had to troubleshoot a problem like this, so I can't give you any suggestions. But maybe the list above will give you some ideas.
- Intake air distribution and filtering components incorrectly installed
- Leakage from intake air system
- Blocked air cleaner element(s)
- Blocked engine breather
- Blockage in intake air system
- Mass air flow sensor seal failure
- Connector is disconnected, connector terminal is backed out, connector terminal corrosion
- Mass air flow sensor circuit, short circuit to ground, short circuit to power, open circuit, high resistance
- Carbon build-up on throttle blade
- Blocked injectors
- Blocked catalysts
- Mass air flow sensor failure
- Using the manufacturer-approved smoke tester, check intake air distribution and filtering components for leakage and correct installation
- Check air cleaner element is free from restriction and in serviceable condition
- Ensure the engine breather system is correctly installed and in serviceable condition
- Check for mass air flow sensor seal integrity and correct installation
- Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
- Refer to the electrical circuit diagrams and check mass air flow sensor circuit for short circuit to ground, short circuit to power, open circuit, high resistance
- Make sure throttle blade is clean of carbon
- Check for blocked injectors
- Check for blocked catalysts
- Clear the DTC and retest
- Reset fuelling adaptions and carry out Powertrain Control Module (PCM) Long Drive Cycle Self- Test
- Check and install new mass air flow sensor as required
