Spark/RPM/ECT question
 

ok, i used my SCT X3 programmer to view the spark, RPM, and ECT of my car. here are the results:

Spark: varies between 20.00 and 10.00
RPM varies between 640 and 730.
ECT was 196.000


does the spark indicate a bad plug? because i changed my Driver's side plugs. not the passenger side yet.
