I'm trying to figure out what "normal" operation is for my new Spark in regards to some rattling/knocking in the driveline. At idle (around 1400rpm) in the water, there is a knocking/rattling sound coming from the driveline. No vibration. It reminds me of what my 96 XP used to sound like. Once you give it some throttle and get over 1800 rpm, the noise goes away.
What does everyone else's Sparks sound like at idle?
