Is your computer tuned for Efans? If it isn't then it might be in limp mode because it isn't sensing a cooling fan.Installed my efans today, but I have a problem. My CEL is on and the gear indicator is stuck on 1. Put the truck into D and tried going forward, but it just doesn't rev at all. My friend's EFILive won't read the CEL code either. Any idea where I fucked up?
