Iceman18T 02-13-2006, 08:37 AM I am taking a guess here, but I'm thinking its the intake grid heater. My truck does the same thing as well. ratlover 02-13-2006, 10:47 AM yup, glowplugs and intake air heater, you can watch it dip down and climb and then dip down again as they cycle jonmaas 02-13-2006, 10:58 AM cool that makes sense and thanks for the quick responce | ||
