Finally after plenty of tinkering my gt is now running great, turn's out that the last owner that i got the car off had replaced the Air flow meter but as he used the old multi-plug, he never cleaned it up or reset the prongs so would not run as it should.

The ecu was brought off jap imports who are from what i've been told a good company so the ecu is in good condition,

Like i say, the only reason i'm selling this hard to get hold of ecu is that i no longer need it, Any good offer will buy.
