Hello, I have a 98 Ranger 4x4 with a 4.0 OHV. Recently it started making this really loud droning/siren noise. It will only do it at or near an idol and only when the engine is hot and the outside temp is hot. Seems to be worse when the a/c is on. The noise is definately coming from the air filter or intake. It has a Roush cold air intake. I changed the filter out with a new K&N but that didn't do anything. I also cleaned my MAFS but nothing. Does anyone know what this could be or has anyone had a similar problem? Thanks for your help.
