P2188

[Jerome]

So I get the p2188 code. System too rich at idle B1

I have a new primary 02 sensor. Checked all vac lines and checked for any boost leaks. New purge valve and OEM MAF.
STFT as pictured at idle is not where it should be (I don’t think) and my HPFP psi is too high. No accessories on or ac or heat.

Yes I did and I recently acquired an OEM MAF and it has been cleaned. Checked for boost leaks installed a new purge valve etc.

You have the maximum negative STFT "-22" Somewhere between the turbo and the throttle plate you have a leak. Your car is trying to correct this by pulling fuel but it can not keep up.

Pre-turbo = + trims, air added or sucked in
turbo to TP = - trims, air lost or pushed out
post TP = + trims, air added or sucked in
