Question about 2001 Nissan Sentra
At second start after cold, it starts fine but rough idle (higher than before problem started) for a few seconds. Pulling power good, fuel good and runs well
I would have the coolant checked for hydrocarbons. If there are hydrocarbons present you have a bad head gasket. The misfire at startup could be from coolant being in the cylinders. This would also explain the loss of coolant with no visible leaks and the inability for the cooling system to **** in coolant out of the recovery tank.
