I have a 2003 ferrari 360 spider with codes p0171 p0174 how to fix

CarDoc :

Hello, I'm Jason. I will do my best to answer your question quickly and accurately using the information you have provided.

CarDoc :

There are two common reasons for these codes, which are long term lean fuel trim codes for each bank of cylinders

CarDoc :

Now, in a number of cars, the air mass meter is often at fault, but since the 360 has two of them, I doubt seriously that both failed at the same time

CarDoc :

which leads me to think that we're dealing with an unmetered air leak, or vacuum/intake leak

CarDoc :

the best way to determine the source is to have the intake system tested using a pressurized smoke generator

CarDoc :

most good European independent shops will have one of these, and it makes finding intake leaks very easy, as you just pinpoint the area where the smoke is escaping

Where should I go ,
Very difficult for me to determine that, but if you can give me an idea of your location, I might be able to offer a few recommendations.

I'm in new jersey in the 07026 zip code
I don't personally know of any good independent shops down there who I could recommend. The closest dealer who's service department is what I would consider reputable is in Edison: http://www.ferrariofcentralnj.com/service.aspx
