tick sound at spark plug wire
buyer of my 91 zr-1 is getting a tick on cylinder #2 , seems to be coming from the spark plug area near cam cover. i have not seen it in person just going by what he is telling me. any ideas? he thinks it's a bad wire, wires have 15-20k miles on wires. coils and spark plugs about the same mileage. seems to happen after driving it for over 30 minutes
thanks todd |

Re: tick sound at spark plug wire
Could be spark arcing to ground. Might be as simple as a loose spark plug wire. Pull the wire off and inspect it. Arcing will leave a trail a lot of times.

Re: tick sound at spark plug wire
See what it looks like when running the engine in the dark. Any cross arking should be clearly visible
