P0302

Thanks

Good deal. You had the forsite to check new parts.
Saw this happen a number of times over the years.
The wires have carbon filiment cores and can break with a sharp bend.
They normally have a measureable resistance to help with radio noise etc.
A check on AM radio often shows it up as a shot noise everytime the cylinder is sparked.
Good luck.
