    MY Idle map KPA is off

    Key on engine off was 0 maf 99 map
    engine on idled at 58-60 map

    now it idles at 86-90 kpa seems very high what could cause this?
    Key on engine off went from normal to 0 maf 50 kpa map

    fueling is off as well sometimes seeing -35 stft

    TPS sometime shows 17 percent at idle

    Sounds like you have a wiring issue to trace down or a bad MAP sensor.

    Thank you john. Ive been dealing with this for a couple months now. Map sensor went bad and did not throw a code. Swapped out the ZR1 map sensor for a 2bar cobalt ss one and it fixed all the issues I was having.
