Hey guys i am having a weird problem, my car started to idle terrible, i looked into issue, and it seems when ever my IAT is plugged in, regardless if i am using any air temp correction it stalls out. I tried to reground the sensor to the ecu and rerun the wires and i have the same issue, the sensor is brand new its a su107, i loaded the provided haltech calibration and still no luck. Anyone else have this issue, also my car idles terrrible once its at the warm map, and breaks up under boost, but i think the break is due to the tune, i have exhausted all my options on this one, i checked the water temp sensor, i replaced the iac, i checked for vacuum leaks, and nothing car is a haltech p2000 on in a s14 runnign a rb25det

sometimes its best to go with what was specified...i've seen new 'oem compliant' sensors read way out of spec fresh out of the box.
