Odd Noise from Air Filter
I have been having a strange howling sound coming from my air filter, a K&N. It only happens when the truck is warmed up or on a really hot day. It comes directly from the filter. Now i searched on the site and found out it could be the IAC. What do you guys think, the IAC, the MAF or the filter itself? I also tried to get the IAC off but it is on there good, any tips.
