Im trying to diagnose a issue and im thinking its a bad map sensor which is a AEM 5 bar. My AFRatioEST and LC1WB are way off at idle. It sputters and dies when trying to drive. I have a key on log and a idle log below. The key on log shows the map sensor at -1.1 and in the idle log you can see things are way off. I was also thinking my fuel pressure regulator may be bad but the gauge on the FPR is fine. In my log at idle fuel pressure is reading funny but I think thats just my cheap fuel pressure sensor taking a dump. Just wanted some opinions here before I go out and buy another AEM map sensor.
