Just replaced the head on my 99 XJ and I put everything back together and fired her up and so far so good! However, the idle is a little bit different than it used to be and I'm not sure what would cause it.
The muffler overpowers the microphone on my phone so its kinda hard to hear on this. I can add another one tomorrow if no one can hear it.
Best way I can describe it, is kind of a 'whoosh' sound or a sound of air coming from the tailpipe. It doesn't sound like that on the video, but you can hear it, it does it about once every second (give or take)
Appreciate any insight! Thanks!
