Codes P0401 and P0441 appeared during emissions inspection. EGR valve and VSV for EGR valve both replaced. Also VSV for charcoal canister replaced. After driving for a few hours and after sitting overnight and after a few more miles check engine light reappeared. Checked and now getting code P0401. What should be checked and what possible repair(s) should be done now to get rid of code?
