Possible MAF starting to fail? Pics of values

**K04-B6** · 06-14-2016 11:44 AM

Hello all,

My car has been starting to have a rough idle in the past couple of weeks. When I'm at a light or a stop, the car just seems to cut off for a second and then bouces back to regualr idle. At first I thought it was my spark plug gap which was set at .28 so I reset them back to .30, that seemed to help abit for a couple days but now it's back to the same rough idle. My car smokes and smells rich which causes me to think it's my MAF, When the car is running and I unplug my MAF the car does the same ''cut off'' but remains at the same rough idle as it did plugged in.

I have a small scanner that I can scan the values but i'm not sure what values are good vs bad. From my research the MAF seems to be reading the right value so i'm at a loss.
These are taken with the car at idle only and at full temp. I don't have a boost gauge either but the car seems to hold boost when it's time to go.

Mods are listed in my sig.

Any help is appreciated!

Thanks

your car is running super lean, your LTFT is almost maxed out trying to add fuel to correct this. do a boost leak test and check for vacuum leaks also.

I had a huge issue over the winter with charge pipes that kept popping off after Intercooler install. All of my vacuum hoses are new. When I had a boost leak the car would not even idle since it would shut itself off... I'm doing an oïl change tonight so I will take a look at everything.
