@mallard8 you sure the fuel rail pressure sensor is plugged in? You mentioned that you kept getting a P008A.

Need to log MAF period to see if the MAF sensor is working.

Who is your tuner?

Okay how can i get that done.
Juggernaut is who is tuning

Your fuel system isn't tuned for your LU47 injectors. So stop chasing ghosts and wait to hear back from your tuner

got it...
thanks for the help.

checked the injectors, looks like I've got the ford performance 47 LB. I wasn't sure what you meant by holes.

What he meant by holes is the bottom part of the injector has holes that the fuel will spray out of.

Whats really weird is your fuel trims aren't changing at all. Your stft will show what % of fuel the car is adding or taking away to hit its desired afr. The ltft will show you the learned percentage of fuel the car is taking or adding away. I see some activity on your ltft which is normal but none on your stft which is very abnormal. Especially with your afr going so rich I would expect the stft to start going negative showing the car pulling fuel.

Next time you log also log commanded afr. Its a good way to see what the car wants the afr to be vs what the actual afr is.

Hopefully its just the injector data and once that's fixed the car will be running good.

Let me know how you like Juggernaut. I've been heavily considering switching to him. My car seems to be a problem car too haha.

LiveLink Gen2 is a pretty nice program to easily view these .csv logs.

Okay so I just flashed a new tune he sent me for the LU47 injectors and was logging an idle like he asked. After about 10 or so seconds my engine shut off and I wasn’t able to crank it back on. Fuel pump??
