Question about 1996 Nissan Maxima
I did a tune up on my 96 maxima one of the spark plugs had oil on it when just running it is fine but when you give it gas black smoke comes out i was wondering if i need to change the 02 sensors?
Ok. Black smoke, mean fuel system too rich.
1 of the problem related come if the car is hard to start in the morning, If is the case, you need to check the coolant sensor and the harnes,
But if the car start normally in the morning or when the car is cool. You need to check for air leak in the intake.
check the hose from the air filter to the throthe bady for crack.
pinched. If evrything is OK. you need a MASS Air Flow Sensor.
