cummins high idle lope log
Not to long ago my truck started to develop the high idle lope, Never done it befor this winter. I have read a bunch online about it, from bad injectors to the ecu dropping cylinders. I happened to be letting my truck warm up and had my laptop, so I grabbed a log of the lope and another after the lope went away. I noticed when the lope was happing my duration was jumping from zero to the 200 range. anyone have thoughts on this? I don't really buy into the ecu dropping cyclinders because this is a recent development
