Hi have a look at this, it might help.
From what I can see, it airflow and crank sensor.

Try here.
Again 74 comes up as airflow.

cheers mate. have had a look and you are correct. crank sensor and the dreaded air flow sensor. will this mean i need to replace the air flow sensor or can it be cleaned.

The definative V6 code list is on this site....:

http://www.omegaowners.com/forum/YaBB.pl?num=1160152415

74   Mass Air Flow Sensor Voltage High and is possibly a rogue code thrown as a result of the failing crank sensor.

Remember that to raise codes the ECU makes assumptions based on the input from all the sensors. So if the crank sensor is reporting slightly lower rpm intermittently (adn possibly not enough to sho on the rev counter) and the MAF is still reporting the correct reading, the ECU will flag both a crank sensor fault and the fact that the MAF seems to be reporting to high a reading.

no way of telling,it could carry on for months or pack up today.probably best not to go too far from home if you can avoid it.remember reading somewhere that TB had one go in the middle of france  :o
