This sometimes happens! Some years back I had various poor running problems, but once sorted, the car has been exemplary. The garage wanted to change the AMM. But they didn't have the correct model. However, after a while he came back and said that they found that it was just the connector. Have they had the correct AMM, then they would just have replaced it for 250 and I would have been none the wiser. I'm quite sure that this mechanic was very good, it only shows that poor running problems can be a headache even for a seasoned mechanic. 1. It could be a connector to a sensor. 2. It could be the CAT. It may be blocked - check if it rattles. 3. It could be the head gasket. 4. It could be a vacuum leak. 5. It could be the DI. 6. It could be something else.
