164 engine hassle
finally the insurance situation in ireland has allowed me to move to a 2.0 164 from a 1351cc 33, about time!
the engine's acting odd - reving itself occasionally at idle (nice regulated, calculated revving), jumping sometimes when in gear (rpm dropping badly but only briefly), and not idling very well. It's not coughing, spluttering or misfiring when it does this, just loosing all rpm briefly.
so far I've changed the oil & plugs, cleaned the ignition leads, distributor, changed the radiator and flushed the cooling system, checked the thermostat, changed the airflow meter and the valve type thing bolted onto the intake manifold from a 75 2.0.
nothing has helped. sometimes it drives fine, with no symptoms apart from the idling, but acts up especially after driving it alfa style.
