Getting New MAF Sensors

Yea i found out the fuel filter is in the tank so hopefully the new MAF sensors fix my problem.

MAF sensors are the MOST over-replaced component on cars.
They are wires that get dirty. Spray them with carb cleaner and I can just about guarantee that the car will run fine after that.

2 MAF replaced under warranty. The 4th start up after getting them installed was quiet and weak. Called my friend who has a nismo and basically asked him "does your car ever start up weak and seem like it doesnt want to turnover"...He said yes he knows exactly what I am talking about, his car after being warmed up seems hesistant to fire up.

I asked for fuel filter check but the tech said it is in the gas tank.

I have top speed y pipe and exhaust and drop ins along with a brand new battery and brand new MAF sensors.

Anyone else think our cars fire up weak and turn over kinda soft compared to other cars and also how strong our cars turn over when cold starts vs during the day after driving?

Hate to have to go back to the dealership and complain but I am 500 miles to warranty and nervous, can i expect anything to be looking bleak or am I over analyzing something that is just inherent in all of our cars
