Keith Browning Posted October 18, 2005 Share Posted October 18, 2005 First, what have you done to address the P1316 code; IDM codes detected? Have you run the Injector Electrical self test(buzz test) and corrected any harness or injector concerns? In looking at the codes P1219 & P1670, neither explicitly mean a circuit failure but rather a communication error or missing or corrupt data. The PCM and IDM share two digital control signals; 1- fuel delivery and 2- a camshaft position signal! Since you already replace both modules an you are absolutely positive that no harness issues exist take a look at your CMP signal. I think you will find that your camshaft position sensor is beginning to fail. I have seen this before a couple of times and it's rare. The fact that temperature affects the symptom supports my suspicions. Please keep us advised on your progress! /forums/images/%%GRAEMLIN_URL%%/hammer2.gif Quote Link to comment Share on other sites More sharing options...
