Codes indicated a EGR failure. The "Service Engine Soon" light has now disappeared. My question is that after installing the new EGR Valve, I hear a loud vacuum (air hissing ) noise coming from near the EGR valve. I do not recall this loud Air Noise from the Engine compartment. This may be normal?
Could you provide some suggestions?
have the same problem?
