[QUOTE="gmac53, post: 7397, member: 626"] check intake, egr, and pull code and see if it is the knock sensors. i just replaced my plugs gapped at .040 wires to coils knock sensors and harness injr=ector rings top and bottom intake gaket and egr gasket now she runs great like rollin off lot, the knock sensors are common to fail due too poor design tsb was put out be cause water would collect near and evetually fill sensor area with moisture/water causing failure. heres the cheapest set up i found for harness and sensors [url]https://www.google.com/aclk?sa=l&ai=CQSZ2viN-VsarMNXKhASGhaGAAerr0OsG0rfC06AB0uiYn5ADCAQQASgFYMnOg43kpKwToAH5973_A8gBB6oEJk_Q3LRb21nU9RJ5puv8nbsojSRUIvVXE3o4GBmizVKjdeZwWjHTwAUFoAYmgAfvh0KIBwGQBwKoB6a-G9gHAeASuNuhuLGk3fe5AQ&sig=AOD64_2xxK6GiII3ago0O1ma1FNj14jYQQ&ctype=5&q=&ved=0ahUKEwj6ubTn4_jJAhUGLyYKHacJBnAQwg8IHw&adurl=http://www.1aauto.com/engine-knock-sensor-and-harness-kit/i/1aeek00589%3Ff%3D808444%26y%3D2001%26utm_campaign%3Dgb_csv_br%26utm_content%3DEEK[/url] btw to check knock sensor without scanner. take and tap near or around sensor area at idle. if idle changes sensors are fine if no compensation is made from the forced "knock then iits bad replace.
