I’ve cleaned the EGR valve, throttle body, and MAF sensor. I do have a P0405 code for EGR sensor circuit A low. MAF sensor reads normal so it’s not that. I installed new intake manifold gaskets not too long ago; I just replaced the fuel filter as well. I’ve also run plenty of injector cleaners over time as I’ve had this issue for like a year. My fuel rail pressure also sits at 39-4 PSI at idle. Any help is appreciated greatly!
