howling sound/check engine light
I have a 4.6L '98 F150 that I installed an AEM intake on, it's been on there for a year, but last week I was stopped at a stoplight it started making a howling sound, it only does it every once and a while and only when I'm stopped, the sound comes from the filter and now the check ingine light came on...has this happened to any one?
