PDA How to adjust timing on 3.4 engine? narksuwan 07-04-2009, 09:47 PM The manual "Chilton" only said hook up OBDII and make sure it's at 10 degree...and then what happen if it not? It doesn't say how to adjust. :confused: BamZipPow 07-04-2009, 10:00 PM I believe the ECU does the timing changes... ;)
