I've had this problem for quite sometime and I'm about to sell the car because I've had. I'm currently throwing code 2AAF (active) and its been affecting my driving (low end and mid range power). I've been told my HPFP, LPFP and sensor is working perfectly and no need to replace any of that at all. I did replace the LPFP sensor last week and I'm still encountering this problem. My LPFP is a stage 2 by fuel it and HPFP was replaced late last year, along with 6 new injectors. I performed a ISTA/D test plan and here's what it's suggesting
Please acknowledge that there are 2 connections that are questionable that connect from the black box to the throttle body and lpfp sensor. What I mean is, that the metal clip came off of one connector last year that hooks up to the throttle body. The sensor connector (plastic tab) broke off last year, should I be fixing these issues? Those connectors havent moved, that's why I didn't bother buying new ones. The lpfp sensor was replaced last week. Don't know where to go from here. Below are a couple logs (93 pump)
