I replaced the EGRt valve but I am still getting an error of " EGR insufficient flow". The new EGR did not come with an EGR valve gasket and the original EGR valve was installed with no gasket either. Do you think that the new installed EGR is leaking because no gasket was installed or there must be other problem?
