Check these first

• A restricted or clogged injector on cylinder 11
• A weak injector spray on cylinder 11
• Air in the fuel rail at cylinder 11
• A worn injector on cylinder 11
• Incorrect injector timing from a wrong calibration

What to do next

1. Compare cylinder 11 injection timing on a scan tool
2. Check the injector balance on cylinder 11
3. Inspect the cylinder 11 injector connector and wiring
4. Check the fuel pressure at the rail
5. Replace the cylinder 11 injector if timing stays retarded
6. Clear the code and retest
