slow car-how to test cis-e/ignition?

[abatzis2@hotmail.com (Michael Abatzis)]

neuspeed plug wires, look ok. tested resistance on the coil wire and one of 
the plug wires, were wnl.  coil also has the right reistance, though i don't 
know how to do a more in depth analysis. don't know about the ignition 
module. i suspect that would be an all or nothing failure, but maybe not. 
i'll check it out tomorrow. any other ideas? again, this came on fairly 
suddenly i think...
