Burned Exhaust Valve MC (Questions?)

[Richard J Lebens]

Is this a 20 valve by any chance?  What did the plugs look like when
you pulled them?  One of mine was black and wet.  On mine the idle did
not change when I pulled the connector off the top of the bad injector
(the cylinder with the black plug).  150,000 mile timing belt? ...
wahoo
The bad news is the injectors on the 20V are $165 each.
