[200q20v] carbon on spark plugs

[Phil Rose]

Asking about (and not specifying) a 10V engine is certainly a 
"factor" in the effort that is wasted to tell you that you seem to be 
using the _wrong_ type of plugs for a '91 200q 3B engine.  As to "why 
a plug gets carbonized"--it was hard for me to understand (from what 
you wrote) just what your question was: carbonized plugs?, loud pop? 
stalling? These might be related symptoms...or not.

Have you checked for any engine fault codes recently? If not, you 
should do so. When was the oxygen sensor replaced? What kind of 
driving do you do-- do you often drive on highway at decent speeds 
and RPMs? Sometimes just getting out and doing that will eliminate 
carbon build-up from short-distance, low-speed driving.
