Yes Dom, its the very same car I went through this with 6 months ago :sad1:

Just remind me if you will what the last answer was, I thought you went back to standard... Seems every time you start tuning her up it throws faults highlighting and underlying problem...
Oh bloody hell... Hope you can get it sorted... Could you try the Ecu on another car to rule that out... Then you'll know it's hardware... If its something like a temp./ cam position/ throttle sensor surely they would give a fault...
Has the timing belt been changed... Worth changing and setting up again?

Theres no fault codes, timing belt was changed last year, though was taken off when the engine was done. all markings are correctly lined up. I looked at the haynes manual, and I think it would be very hard for the timing belt to slip past the key?
Last time the cams wer incorrectly lined up, it didnt throw a fault code either. I did have a fault code a few weeks ago
000017 - Bank 1: Camshaft A (Intake)
P0011 - 004 - Retard Setpoint not Reached (Over-Advanced) - Intermittent
000022 - Bank 1: CMP Sensor (G40) / Engine Speed Sensor (G28)
P0016 - 008 - Incorrect Correlation - Intermittent

Ive not given up yet, determined to get this one solved. Theres some very odd things going on with the ignition advance at idle that dissapear when you engage drive.
A test of TDC position vs crank alignment marks lead me to believe that the crank wheel has not slipped.

Is there the slightest chance that the ECU has gone a little corrupt? is has been flashed once or twice?
