Broken Spark Plug Wire Repaired

3/10/07
mileage = 78639

The fuel mileage in my Civic had dropped from 30mpg to about 25mpg, so I finally checked around under the hood. The last thing that was done before the drop in fuel mileage was replacing the spark plugs and installing new tires/wheels. I took an ohmeter out to measure some resistance and I found out that one of the spark plug wires was broken. This forced me to get a new wireset that day. I ended up getting a Bosch wireset from Autozone for about $55. Ideally I would have got some NGK wiresets, but none of the stores carried them.

Fuel mileage went back up to 30mpg on the next tank of gas, but after that the mileage went down to 27mpg.
