Can anyone help me narrow down why this happens? My Jeep sounds like it’s chopping with a cam HARD with fluctuating RPMs at idle. I think it’s a fuel issue. Any suggestions? Thanks
Here’s a link for the sound clip : https://youtube.com/shorts/C8zBNyhmjs0?feature=share

 

Is the engine stock ? or whay has been done to it . Like does it have a exhaust system on it or anything else .

 

I just have a chopped exhaust behind the cat, other than that it’s stock.

 

Sounds like a missing muffler to me. Maybe a gutted cat too.

 

With the its hard to hear what's going on . Have you checked for vacuum leaks ?
