Hello Fellow Alfistioso,
In a previous thread we discussed how my 91' Veloce was idling rough, and stalling at startup. Many, many ideas were presented, and my thanks to all of you (you know who you are) in helping me to gain great knowledge on the air, fuel and fire of the Alfa engine and systems.
So what was the culprit? Bad IGNITION COIL. The IC rubber boot on top was worn and torn, and the new IC coil worked like a charm. The ONLY small issues I have are inconsistent non-stall variations in idle when the engine is warm/hot, less than 200 rpm. That can be fixed with a new IAV going into the plenum. Car runs solid and like a champ!
So what did I get out of the whole ordeal you say? New in-tank pump and sending unit, new O2 sensor, new crank position sensor, checks on all air and fuel systems, ECU relay box check and the mechanic knows the car really well now.
Today's December drive in the car was fantastic.
