Hi, my 2000 Nissan Maxima wigth 75K miles on it does not idle steady and stalls on cold marnings with temp outside below 38F. It sounds like one cylinder misfires. Once the car warms up the symptoms disappear and car runs fine all day. Mechanic noticed oil on one of the spark plugs and suggested that oil is leaking into one of the cylinders. His resolution is to look into leaking valves/seals/rings and replace leaking parts. In best case scenario the repair should relatively inexpensive but in worst case I am better off replacing the car. What part(s) exactly can be leaking and how series is it? There is no suspicious smoke coming out of the tale pipe at any time, smoke color and quantity seem to be normal.
have the same problem?
