My civic has a nasty rattle that only really happens under two scenarios:
1. Car idles at around 500 - 600 RPM, when it goes below 1000 RPM on the idle, this is usually when the rattle starts
2. Low RPM at a low speed in a higher gear. If I'm at.. say, 25 MPH in third, I might hear a little rattle when the the car fights to get a little gas.
In both situations, when the car is happy with the amount of fuel it's getting and stops idling, it's totally fine.
Any thoughts on this? Unfortunately this developed only after adding DC 4-2-1 headers and a Megan high-flow cat
