My '75 1.8 L-jet FI car starts and runs very rough when cold. If I wait less than 5 minutes idling it for warm up before driving, it stumbles, sputters and dies. When cold, if I give it a little gas (2000-2500 rpm or so in neutral) it won't settle back down to idle; it drops way below idle speed and often stalls. Is this normal? My odometer also stopped working the other day. The speedometer still works, but the odometer does not. What are there common causes for this?
