Ok if one is testing the coil wires on a 89. What should the multi-meter read? Should be 1000 total, or 2000 ohm total for both ends?

My impression is that the only resistance in the secondary wiring is in the plug connectors, so would expect very low resistance readings on the coil wires. It will be interesting to see if my impression is wrong...

Measuring plug to plug I got results of 2k ohms

Ok that"s what I got. Been trouble shooting a car, and every thing keeps coming up in spec. Found the issue.

Mass air meter position. It's new but seems to have an air flow disturbance in the lower mid range. And just got a new FAST air fuel box in the mail. As I tightening up the spark plug gap it ran better so I thought it was spark related

Interesting. Ignition cables in good shape ?
Nice work.

Yep as coils test in spec. Going to open the gap back up an see what happens. Also supercharged.
