I received my Range today. I plugged it in and took the Hoe for a test drive. No more rough idle, the V8 to V4 shudder is gone, and a CEL light turned off. This is the best $ I have spent. Before I ordered my Range I made an appointment for the oil consumption test. The dealership told me its normal to add 3-5 quarts in between oil changes. Really!!!! 3-5 quarts. Now I'm hoping this will fix the oil consumption issue. I wonder if I should still go forward with the test.
