[QUOTE="CalBoy101, post: 13889027, member: 154279"] I just installed a new 2.1 KB on my 2002 GT and I'm shaking it down to make sure its running right. I'm getting a weird whistling sound around 1000 to 1200 RPM, listen to it in the video below. I don't think its the standard KB whine, I can hear that as a separate sound. In the video below you hear the KB whine more when you rev the engine up and then the whistle more as the engine revs down. Its also idling a little high in park, a data log shows it should be idling at a commanded 750 RPM but it only comes down to around 825 RPM. I've tried capping the PCV, evap and EGR vacuum inputs and also tried blocking off the IAC but whistle stays there. I also tried squirting brake cleaner around the base of the manifold and around the injectors but no change in idle. When I disconnect the IAC electrical connector the does drop to around 700 RPM but the IAC is an almost new Motorcraft and it was working fine before the blower install, and the engine was running and idling perfectly before the install, the plugs looked perfect. I've never heard a KB run before, is this whistle normal or do I have a leak in the case or under the manifold somewhere? [ATTACH=full]546111[/ATTACH] [/QUOTE]
