P0172

[ItzCroix]

Hello, Im new to the forums but I recently got the Code P0172 I have cleaned the MAF and haven't been able to do anything else. Is there anyway to tell from datalogs what the issue could be? I have a high LTFT reading and wanted to know where to go from here. Any help would be greatly appreciated.

I had this code pop up as well, along with a P0455.

Here's a 3rd gear pull after cleaning the MAF, first log was before in 2nd gear

you have a rich code at idle but it get lean under boost, i would be careful until you solve the problem as small knock can be seen under boost probably related to this bad afr.
it is usually related to a piping leak or ecm tune not compatible with the installed intake. cheap one without air straightener is likely to make this of different size etc...

It is helpful for you to list in detail all mods to your car, tuning choice and map, if not stock, and whether you’ve made any recent changes beyond cleaning the MAF sensor.

If that is a Cobb OTS Stage 1 93 octane tune, what mods are you running with it?

We need a LOT more information.

What map are you running? We can't tell you anything if we don't know what calibration you're using.

Stage1 93 v260, Sorry I thought it was in the datalogs at the top

Did you add any of those mods or make any changes right before throwing that code? How long had it been running well before hand?

Do you have older logs made before the problem we can review for comparison?

[ItzCroix]

No Older Logs, I had to reformat my PC and lost all of my logs. It has been running great for 3-4 years now. Newest Parts added was the Solid Motor Mounts about 6 months ago. Just recently has that code popped up.
