Because the initial thread began as a general inquiry about sparkplugs and
then kind of moved around, I thought it best to start anew....
re: 2000 C70
Car running rough, thought was it needed new plugs...
Bought a Equus 3030 and here are the results - codes off the unit,
description off of Volvoforums.org:
P0302 Cylinder 2 Misfire detected
P0352 Ignition Coil B Primary/Secondary Circuit Malfunction
P1550 PSPS Out Of Self Test Range
The plot thickens?
