These are the codes that I read last night. My interpretation of the data posted is the following error codes:

4 Air injection system faulty hot film mass air flow sensor with hot wire
5 Exhaust gas recirculation faulty
19 Injectors circuit open or circuit short emission control module adaptation in engine control module at limit


My questions are: is my interpretation correct?
Does anyone have suggestions on next step?

Thanks

John
