I am working through an at speed / acceleration stumbling issue that gets worse when warm. I’m investigation if the 4 year old plug wires are all still good but have practically no expertise with multimeters. 3000 ohms is printed on the wires. I selected the meter as shown below:
Wire 1 resulted in 1676 displayed (don’t know the units)
Wire 2 showed 1346
Wire 3 showed OL
I wonder if three is an open loop because the car starts and runs well.
Am I doing this correctly?
