Yeah, Aside from the tank pump, I looked at IAC valve -- seems OK per test sent by Grant...Temp time switch goes on/off per temp...(tested for continuity after letting it set, and when warm - seems OK)...AFM swings freely & idle changes when you unplug it -- seems OK(?)...adjusted throttle switch - definetly improved low-end drivability! seems to start OK when Cold or you shut it off then back on within a few minutes...which reminds me - is it the in tank pump with check valve or other???? I'd assume the E3900 would have one? I have a new temp sensor coming (this somehow controls fuel injection, so I'm crossing my figers)...any ideas? Thanks -Aaron
