My Tipo 1.4 DGT ie CAT from 1989 (52.000km) has 2 electrical valves connected on back (behind) of engine.
(see picture, I removed the plastic cover cap on the picture).
Valve nr. 1 is often ticking or vibrating like crazy during idling. This goes on and off. No specific pattern. When I take of the electric connector from valve 1 it stops stickling or vibrating. Maybe during driving the car it happens also but cannot hear it because to much other noises.
-
Question; Can anybody explain to me the use and or purpose of these 2 valves? Valve nr. 2 is 7539889 and is also used in other Italian cars like Lancia and Alfa but i've seen it in many different discriptions.
A good explination will be very much appreciated because in The Haynes repair manual (and others) I have, it is not documented, only carburator version and my Tipo has a single fuel injector sytem.
Thanks in advance!
Best regards
