I am luckley enough to own a 1994 Sedicivalvole 3 door (1 of 15 imported into New Zealand) but there has been an ongoing problem with the cold start idle. Everything relating to the cold start idle has been checked or replaced but the problem persists. The duty cycle going to the Air Idle Control Valve is all over the place and way out of spec.

I have discovered the ECU in my car is Magneti Marelli IAW 4Q5 and it looks like it has come from a car wreckers. My research tells me this is from a second series Lancia Delta.I know the first series Tipo 2.0 16v had IAW 1Q4 but my question is does anyone know what ECU the second series had?
Any help would be much appreciated.
Regards, Darrin.
