Hi, I own a 2002 base rsx automatic 128k miles. After driving around in stop and go traffic, I hear a rattling noise/ clicking noise comming from the engine. The noise ONLY comes at very low speeds (<10 mph) or when im idling in neutral. If i just drive a short distance, I will not hear...

When I first installed the motor mounts I had a pretty loud rattle whenever I was starting & let the rpm dip too low below idle. Maybe around 500-700.. After I removed the shields by the header the rattle definitely happened less, now only around 6-500rpm. I don't bog the car like this regularly...
