Hi all,

I've had a misfire for a while now, on idle it is in Cylinder 1, but spreads in high rpm.

I took it to an independant to have diagnosed and they determined it is plug wires.

Are there any recommendations for brand, I know Bosch is a good choice but I'm struggling to find a full set.

Any input is greatly appreciated!!!!!!!!

 

Are the spark plugs new or in good condition?
mixture adaption shift? Left and right bank? How can 12 plug leads be faulty! Airmass value?

 

Plugs are good, changed just a couple months ago and the shop verified.
The wires in 1 are bad, and all other values looked good so there are probably a couple bad in other cylinders.
at higher rpm 4 5 and 6 start to stumble
from what I found it is easier/ cheaper to buy a set as soon as you need more than a couple

 

They are sold individually as they are not all the same length
