Hey all,

I recently got a new Civic Si 2020 (first manual car) and I noticed today that if I get going in first, and then very soon after, clutch and brake, the car rattles 3 or 4 times very lightly as I'm pressing down on the clutch pedal (no gear shifting is involved).

I could imagine it sputtering if I was engaging with RPMs too low, but this is consistently when I'm pressing the clutch in and disengaging from the engine, so I'm a bit baffled. It doesn't seem to happen every time, and is only noticeable with 1st gear, but it might happen with the others and it's just that the car is moving too fast to hear/feel it. Is it maybe just the car blowing off exhaust from running rich or something? Not sure if I should take it into the dealership quite yet, would appreciate any hunches or things to try.

Cheers,
Jengerer

Weird, I went out again tonight to try to get it on video, but wasn't able to reproduce it. I had gone out earlier to practice my starts a little bit, so maybe it's something particular to repeatedly starting and stopping, but can't imagine what it might be.
