I have a spark plug wire issue....I dont know if they need to be replaced or not... The car has a lot of rough running issues... 305 V8 non-computer year unknown....

Here is some Ohm readings I took today from each plug wire... Maybe some one can look at these and give some insite....

Plug wire: All figures are in Ohms and inches in length....

1--38 inches--1,590 ohms>>> ohms per foot===502
2--34 inches--1,370 ohms>>> ohms per foot===484
3--33 inches--1,300 ohms>>> ohms per foot===472
4--29 inches--1,150 ohms>>> ohms per foot===475
5--22 inches--2,420 ohms>>> ohms per foot===1320
6--34 inches--1,390 ohms>>> ohms per foot===490
7--38 inches--1,580 ohms>>> ohms per foot===498
8--31 inches--1,440 ohms>>> ohms per foot===557

The wires are Accel 8mm.....

Are these number good, bad, or what......Wire #5 seem different compared to the rest.....

 

Number 5 should be replaced.

 

Does Accel sell single plug wires? Thanks for the reply....

 

Look at Nology wires. They are expensive but are way ahead of there time.

 

thank you

 

you should be 500 ohm per foot, acdelco usually have 150 ohm a foot and msd makes ones with 40-50 ohms a foot.
