    7.3 IDI idling at 100RPM

    Hey everyone, new to this forum, I’ve got a ‘94 f350 with a non turbo 7.3 IDI, 127,000km on it. She shakes more than I think is normal at idle and my tach shows 100RPM at startup, MAYBE 300rpm during high idle (slight bouncing of the needle as well) when it’s cold and it seems to lag some when...
