Ok, here is the story. I was driving fine and dandy when all ofthe sudden my engine starts bogging and suddenly it shut down. I had to wait a couple of minutes before I could get the engine started again. I didn't noticed untill today that the afc wasn't reading the afl. I did a sensor check and it was showing voltage coming in and out. I'd have to go back and jot down the readings i'm getting. I checked the connection theyre fine I swapped out the Air flow sensor and nothing. I also noticed that when throttle position went past about 5.9% the engine would start to stutter and bogg. I hope it's not the afc, is there anything else you guys can think of? No cel is actively on, when the phenomena first occurred a cel did come on but went away after I turned off and turned the car back on.

how long have u been having this problem? since boost? since SAFC?? which type of TPS sensor do you have??? my problem i was getting at first, because i had my addtional injector wires wired in firing instead or cyl order or vice versa, was that when i would give some throttle, usually 6-15% and then it would flood engine, bog, and die.. do you have a wideband readout?? or just a lil AFR guage?? on the SAFC can you check what your duty cycle goes to at that point. cuz my bad wiring it shot up to 100% duty cycle at those instances.. do u have any type of datalogging ability??
check the voltage that was coming in and out of MAF, at idle mine are about .90ish and with car off like .16-.17ish
