WHAT ARE THINK ABOUT ECM BEING BAD
Customer: replied 7 months ago.
I ALREADY REPLACE WIRE GOING TO CAM SENSOR
Expert:  john -aka eauto replied 7 months ago.

Its not likely the ECM it is possible but very unlikely and you would have to follow a test chart and would need an OHM meter and a good scan tool that read live data in order to test for that. I can get you the information on that if you'd like but with out the necessary equipment then its not going to do much good but like i said its very unlikely and checking those wires is really the first step. You are either going to have to pay a dealer to that a buy a good scan tool and OHM meter as well as familiarize yourself with those instruments so a hour or 2 at a dealership may be your best bet.
