Hey guys, I recently purchased this ej1 with the stock d16z6.
I don't know what maintenance has been done on this car, so I decided to check. I was testing the spark plug wires with a multimeter and these are the numbers I got for the resistance.

Cylinder 4 - 6
Cylinder 3 - 8
Cylinder 2 - 9.5
Cylinder 1 - 11

How are these numbers?
Should I replace them?

 

Just replace them with new. Do a full tuneup since you know nothing about the vehicle history.

 

-Connect ohmmeter probes and measure resistance.
-If resistance exceeds 25 K Ohm , replace the ignition wire.

 

What units for the measurements - Ohms or KOhms? Regardless, they test fine.

It's also important to inspect the wires for cracks in the insulation.

 

What is the proper setting, my meter has 2k 20k and higher, I assume higher?

 

Start at the 2K Ohm range. Depending on the reading, switch the range to be closest to the initial reading, if necessary.

 

Probably best to replace them. There is always the possibility of a break in the insulation even if resistance values are good. If you know nothing of the car's maintanence history, where its been or what type of owner the previous person was then replacement can be peace of mind.

 

Thanks guys!
