Today I plugged my heater in from 8am to about noon (forgot it before I went to church). Came home, started it up and it smoked white for a minute. I drove for 3miles turned it off. Went back out and it cranked but would not start. I let it sit 3 hrs and tried again. After much cranking it started. More white smoke, idled very rough at 500 rpms. It doen't seem like it is running on all cylinders. Oil is Ok. Antifreeze is down about 2" in the radiator. Did leaving the block heater on too long do it?? It was 20 and then warmed to 35 degrees today. Any ideas??
