Car Struggles to Start when cold starting but once the car is fully warmed up then it has no issue.
the car will stall multiple times and usually have to hold the gas pedal down a little so car will not stall and almost seems like it is starving for air.
I have a 2000 Nissan maxima GLE

I have replaced the valve cover gaskets
cleaned the throttle body and cleaned the iac
all new spark plugs

 

I hear a vacuum leak, sounds pretty loud, which could cause uneven idle and stalling. Spray soapy water around all your hoses and fix the area you find bubbles. Also good idea to check air filter and clean maf sensor

 

I will have to try that later. When I replaced the valve cover gasket. All of the hoses did seem good but I will spray soapy water everywhere to see.

I do have a have cel for an o2 sensor but I don’t think that will cause it to stall.

im not sure if the video shows it but also there is a popping sound from the cylinders which is unburnt fuel but could Indicate a bad coil, but I don’t have a code for that yet.

 

Check if your MAF Sensor has a green dot sticker on it. I do not see one in the video. If not, you should replace it with a new OEM MAF sensor. That is a very common part failure on these cars.
