Just got done at the Mazda Dealership,
The came up with an Diagnostic Trouble Code P0730 Incorrect Gear Ratio
The last step of the diagnostic - 5 reads if no reinspection diagnostic trouble code appears: The problem is a temporary slip of the clutch, and should be investigated further.
After driving back from the dealership; no engine graphics re-appears!
I am going to sell the Millenia; for right now! (It has 117K and I don't want to shell out possibly $1,500 or more to try to fix it!)
If someone else thinks I should fix it or keep the car; let me know!
