Default Getting New MAF Sensors

Took her in today for intermittent weak turnover, light sputtering at idle at stop lights sometimes.

Thought it was Fuel Filter/ Pressure.

Apparently my MAF sensors were reading bad causing bad air/fuel causing the problems. Getting new MAF sensors put in so we will see what happens and if the problem is fixed.

Figured the weak turnover/ sputtering had to be either ECU, MAF or Fuel Filter

There's no servicable fuel filter on a 370.

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

What you guys think of this.

As far as the maf this what the tech sheet said
"checked data monitor alphas very low cleared self learn and performed iavl, af's returned to very low very quickly, confirmed maf failure, replaced maf's.

After I left the car still turned over quiet an SLOW. Jordo said our cars take longer than othe cars to start up. He knows his stuff but wanted to get your take on the tech notes
