Im having an idle issue on my msp itll idle fine for about thirty seconds then drop and act like its running out of gas. I just did a front mount intercooler and relocated the maf. Cleaned egr, throttle body, and iac. I dont know if its related but above 3800 it feels like its running super rich and kind of feels like its getting to much fuel. Ive checked the idle with a scan tool my LTFT is around -25 and +9 on STFT but when the bad idle starts the STFT goes to zero and on my tool where it tells me if Im in closed loop or open loop its says open loop fault. Any help would be appreciated.
