2007 Xterra SE - Anyone dealt with and solved the infamous wont start in cold temps issue. Still having it despite new battery, new fusible link, new pos and neg battery cables, freshly buffed clean ground points, and over the last couple years redesigned IPDM, valve cam and flywheel sensors (which did fail and a was separate issue), plugs, and is perfectly maintained? Many people think it is a bad ECU but obviously hesitant to go buy a new $1000 one. Anyone send an ECU to one of the test / repair services? Anyone heard of an ECU reprogramming to address this issue? I did see at one of the test services they list Maximas as having a no ECU communication in cold temps issue.
