    So Im having some stalling at idle problems. When it stalls sometimes it has thrown a P2188 CEL. I've chaged my fp relay (opended and they don't look bad) and the fp resistor and it made the cel go away but only for a few days, then it came back as did the stalling at idle. As I'm monitoring stuff on my ap I noticed the the hpfp sensor voltage is reading 0volts and stayed that way they entire drive home.... What causes this and could this be the cause of my random stalling at idle. Also when is says hpfp sensor do they mean the fuel rail pressure sensor any and all help would be amazing. I also have a new in tank fp I'm putting it to see if that help cause I was told by someone on a fb group they had the same issue and replaced the relay, resistor box and in tank fp and that fixed it but just trying to cover all my bases

    Try cleaning your MAF sensor, have you got a way to read fuel pressure? What's the hpfp pressure reading before it dies at idle

    I already cleand the MAF, that was the first thing I did.
    I have and access port and the pressure is fine before it dies no change... It's like I've just turned the car off. When it dies all the dash lights come on as if you first turn in it to the accessory spot on the ignition.
