Customer Question

i am getting codes p0455 and p0457, i need to smog and i don't have access to a smoke machine.. any ideas where i should start?
JA: Do you have a scan tool to read the codes?
Customer: yes that is how i got those codes
JA: What is the model/year of your Ford?
Customer: 2001 ford focus zx3
JA: Are you fixing your Focus yourself? What have you tried so far?
Customer: i do all my own repairs.. so far all i have done is hook the egr line back up to the exhaust manifold and egr valve and make sure all electronics are connected and that none of the lines are visably damaged, i checked the filler cap to make sure its seal isn't damaged and that no debris was in there, im really short on time, i was curious if there was a common issue that i could start testing components and move forward from the most common to least
JA: Anything else you want the mechanic to know before I connect you?
Customer: i dont think so
