The best place to start is with checking the fuel system for proper pressure and volume.
The pressure spec for your vehicle is 49.2 psi ± 5 psi and the volume spec is 1/4 liter in 7 seconds.
If the system isn't providing enough fuel to the engine you end up with misfire codes.
You may also need to remove the fuel rail and check it for contamination......dirt, grit etc.
Complete fuel pump ass. was replaced 3 months ago, I ll have to check pressure. the problem does seem to clear up when van warms up.
Ok and the volume test?
These tests are best done when the vehicle is acting up.
