Well, my car won't idle for some reason. The AEM EMS seemed to help it alot once i got the car tuned, but for some reason all of a sudden, the car just won't idle, if i take my foot off the gas it will stall, or at least sputter VERY low in the rpm range (300rpms) and try to stall. This obviously makes for a crappy driving experience, it also seems like lately my fuel pump has gotten much louder (walro 255). Have any of you guys experienced the same or similar problems?
