Since I got the car back, I have removed the spark plug wires and tested the resistance of each one. Each measured about 6.5 kohms (some were 6.3 or 6.1 and others were 6.7 or 6.8), except for the number 2 wire on the driver's side. I cannot get a reading for that wire, the meter shows nothing. This is hard for me to believe and I have tried it several times, but still nothing on the meter.

The distributor caps also give some wierd readings, so I'm looking at replacing those and the rotors.

I also tested the ignition coils with the following results

Left side - driver's side
primary - .7 ohms
secondary - .9.83 kohms

Right side
primary - .7 ohms
secondary - no reading

The bentley manual says
primary - .37 ohms
secondary 9.0 ohms

Do you think that the primary is bad (.7 vs .37)? Looks as if the secondary on the right side is bad. What kind of effect would that have?

Another question, the bentley manual mentions the part number for the ignition coil as 20510171101. The coil on the right side has this number, bu the coil on the left side ends with 02. Should the numbers match?

Any help would be appreciated

Regards,
Keith
