Complex! 2006 Lexus SC430, running perfectly. Suddenly missing, scanned, "misfire cyl 5." Couple of days later, running rougher, scanned, "Misfire cyls 1, 3, 5, 7." Couple of days later, wouldn't start, scanned, "Problem with camshaft position sensor circuit, " "Problem with crankshaft position sensor circuit." Checked continuity of both circuits, tested good. Changed the camshaft position sensor anyway, no change. Engine fires very briefly, then shuts off. Stumped!
