as follows:

#1 6.0 Kohms
#2 6.55 Kohms
#3 6.59 Kohms
#4 27.0 Kohms
#5 6.59 Kohms
#6 6.58 Kohms

Coil wire 2Kohms

Imprinted on the distributor cap end of the spark plug wires is the number 0 300 513 120. Also, printed next to this number is 1Kohms. Is this supposed to be a good reading? My baseline of about 6.5 Kohms indicates that #4 wire is bad. The car only occasionally backfires and runs strong at any rpm above 1500. WHERE CAN I GET WIRES and what the hell is the function of the little wire clipped onto #1 wire? New Bosch plugs are on the way (WDC8s).

Note: Measurements taken with Fluke77 multimeter in auto-ranging mode.
