Spark knock
I have a 2002 Camaro SS. I've noticed the engine will have a bit of spark knock when first started, lasts for about a minute. It will also do it at some other random times while idling. The car only has 22000KM and the engine runs strong and smooth. I've heard this noise from some other vehicles with the LS1. Any suggestions what this might be? Thanks!
