3 things.

1. Pull codes even if no CEL is on. They can be pending but dont drive it if you can. buy a code reader

2. check oil level. could be that its too low for VVT to properly work

3. internal failure. if the oil is plentiful and of quality, youve got issues and will need a teardown to find them.

What codes? I'm thinking a high pressure fuel pump issue. Post the codes
