I wouldn't go to assuming the ECM was faulty. No evidence of that.
I wasn't assuming the ECM was bad. I was merely saying that the ECM MAY be bad. That's why I asked if he cleared his codes out.
OK, he's getting codes referring to his EGR lines and O2 sensor. Lines are fine, O2 sensor replaced twice. If the codes aren't erased, obviously, they will still be there. Let's assume the wiring on the vehicle is OK. IF the codes were cleared and said components are either new OR checked out and are fine, and the ECM is throwing the same codes, the ECM may be malfunctioning.
