Following things have been done for this -
1. Intake manifold gaskets has been replaced.
2. IAC valve has been replaced.
3. All the hoses (PCV) have been replaced.
4. Throttle Body has been replaced.
5. Smoke test done for checking vacuum leaks and there are none.
RPM has come down from 1200-1300 to 900-1000 now.
However the check engine light is on again with same code.
Also, EGR and EVAP is failing in OBD2 readiness.
What am I missing?
