The codes have been cleared after the original work was done so the codes are relevant, also have seen multiple misfire codes and the anti pollution light illuminate first thing in the morning when the vehicle runs at its worst.
After its warmed up the engine seems to run fine just the issue with the very low Vacumm?
Emissions are as follows-
Idle
CO- 0.004%
CO2- 15.38%
HC- 0.00%

Cruise
CO- 0.010%
CO2- 15.40%
HC- 1%

Sorry no O2 at the minute will try and get reading sorted
I am still leaning towards possible valve damage but not confident that this slight damage which dosent appear to cause a running issue when hot, could cause this very low Vacumm?
