AUTO MECHANIC PROBLEMS (AGAIN)

[terracore]

Are you sure it's not stuck in 3-cylinder mode when it's supposed to be in 6-cylinder mode?

That was/is a common issue with those models.

I've never heard that.  6 cylinders is the computer's "safe mode".  The car won't go into 3-cylinder mode if the check engine light is on or the computer detects any errors.  (It is common to hear that these models won't go into 3-cylinder mode).  The car isn't showing any errors, but I run it with the "current MPG" display running which also displays how many cylinders it's using.  So far it seems to match what it's supposed to look like.
