So I have been trying to troubleshoot my car. Ive been having a sputtering issue when I try to push the car. I dont know what it can be. I had recently done an oil change, changed the plugs, put fresh gas in it, and I installed a new oil pressure sensor because the old one was leaking. Anyone have any idea as to what it can be? I did a boost leak test just to make sure but I have been building good boost. I am running a Forge RS bov and a forge wastegate. Any help would be appreciated. Thanks!

 

Im thinking it could be fuel pressure loss.You have an afr gauge to give some numbers?

 

i attached a video of the afr

 

hmm all I see is an audio file I hear the sound..

 

the afr shoots all the way to 10

 

Looks to me like its probably rich and that might be causing your issues.

Is the AFR 10 when its stuttering?
Do you have a way to log the car for knock, AFR, timing, etc?
Is the car tuned?

 

This is normal if the car is tuned that way. My goes to 8 AFR when I push it hard.

 

My afr has always been like that when I go. It sputters up on high rpm so Im not sure if I should start by checking the fuel filter or checking injectors

 

What are the plugs gapped to?
