Recently my car was stuck in the snow and was leaking coolant while I was trying to get out. after I got it out it stalled out on me and didn’t start afterward When I got it running again the engine light came on with cylinder 4 misfire. At idle it’s very shaky, but the car seems to run fine, coolant has not leaked since. But I can’t drive even 1km before the engine light starts flashing at me. It was parked all day yesterday because of it and when I went to start it this morning it was turning over but didn’t seem to want to fully start. Also I turned my heat on full blast and it sounded like a train was passing through my driveway. I have no clue what the possible cause for this could be, it was running perfectly before it was stuck in the snow. I feel like it may just be a spark plug issue but that doesn’t explain the heat problem.. any ideas?
