Can you graph like this with your scanner. It's probably normal to get a half volt drop but not a 1v drop. I got drops to about 12v when my alternator slip rings while being worn out also got coated in oil. I replaced the rings and brushes and no problems since. |
Yes, that's the graph I was recording when I saw the dip in voltage. However, when I go into the scanner and pull up saved data, it won't show the graph, it just shows data points and you page forward and backward to go through the timeline.
I'm sure there's no harm in putting a new MAF on. I think I'll try that. It's 144,000 miles now so I'm sure it's something that will need replacing sooner or later anyway.
