Hello all, hope everyone is healthy. I have a odd sound. On my 2017 Mustang GT with the JLT CAI and Tune, I noticed recently while jump starting my pickup, that I had this odd thump. It sounds like it is in the intake tube to the throttle body. Obviously there are no moving parts inside the tube. So something is creating the noise and the tube is acting like bass tube.
Odd Intake Tube Thump
It can be hard to hear, but it happens multiple times
1st - at 11 seconds
Then repeats at 16, 19 and 22 second mark.
I'm having a hard time identifying where it originating from. I THINK, it is coming from somewhere around the TB (which is stock and manifold is stock). Ive read other posts in regards to people having issues with TB. But couldnt locate a good video of the sounds being made. I also dont have any idling issues that I can tell. It idles fine, car seems to drive okay. It has been rather hot here in SFLA the last few days, today it seemed a bit sluggish on light throttle. Havent stalled out at all. Or seen a noticeable drop in RPMs. I've also read people stating the purge valve?
Happens regardless if A/C is on or off. And does not go away with driving. Pretty much is there all the time, however the frequency of it seems rather random.
Thoughts from the forum on what it could be?
Regards
Steve
