Hi!
I had this code come on now for a while, oc2 was change and code P1070 in 01 & 02 keep coming up, usually after the car has run for quite a while. I saw on the tech post references to the air flow censor, and my guest was of the egr valve or the thermal switch to the valve, is this correct and can you tell me exactly what it may be and the fix?

Thank you
