Codes ?

P1338, P1340, P1338 and 05FF the mechanic who ran the test reset all and it worked fine ......till next morning

I could only suggest plugs or coil pack issues? Intermittent multiple misfires bank 1 can mean one or more cylinders are not combusting correctly maybe swop over the plugs & coil packs in 1 & 4 see what happens

The codes don’t suggest this, but has the HPFP ever been changed?

Not to my knowledge, but the repairer did replace the coils and spark plugs. That worked for a day and back to
The old problem. Rerun of tests and fuel pump now identified and replaced Problem solved except for the hefty price tag… $2100 Australian pesos
