I disagree Gambalunga. Just to fob off with no friendly attempt to help is a good indicator of attitude. Had he worked for me and responded like that to a query, he would have been disciplined.

Anyway someone else I spoke to suggests the likely culprit is the mass air sensor. If the OP disconnects this sensor the car should still start and run albeit maybe into limp home mode. However if he does disconnect the sensor and the car does start it indicates that the sensor is the likely culprit and worth replacing.
