Hello, im having trouble with this 2007 saturn setting a p0016 code after a timing chain replacement. The car drives fin other than a rough idle. code will only set at an idle and not while driving. Need to know if there is a reflash procedure that needs done or where to go to further diagnose the issue. p0016 snapon scanner is calling it a CMP actuator malfunction p0016 Matco scanner is calling a Control module long term memory reset
