Freaked out due to IMS reports - Newly discovered engine noise

[coreseller]

Another possible way to correlate your noise to the bad engine mount......when I bought Pedro's Enthusiast's Mount which is stiffer than the original, the vibrations I noticed transmitted to the butt sensor after the install occurred between 2800 and 3200 rpm's. Per other comments this is not unusual, which tells me this is a natural rev range to transmit vibrations.
