check engine light

[Jon Meckem <meck@sprintmail.com>]

The check engine light on the 5ktq is intermitenty coming on.  There
does not seem to be much of a relationship between the light and
boost/rpm.  The engine is not pinging or knocking.  Is there a sensor or
conection I can check?

Also, I have the drive shaft out of the car right now, with the front
diff locked (that was the only way the car would move) will this cause
any additional wear to the front diff.?

Thanks for any help...
