Hello, I am new to this forum. I have a 2008 Wrangler X manual transmission. It’s been making a flutter type sound that gets worse after it is warmed up completely. I noticed the exhaust manifold does have a bolt head that is busted off and I plan on taking the manifold off and getting it out to replace it but idk if it could also be the rocker arms or valves. If I hold the pedal down even in neutral it has this flutter sound that is really intense. I have someone hold it down while I felt around to try to locate it and the exhaust manifold vibrates and shakes. It also sounds and runs terrible at anything above 2500-3000 RPMs. It’s only the passenger side that’s doing it I’m pretty positive. I bought it used in the fall and it’s gotten worse since then a little bit. Anyone ever had anything similar to this happen?
Thank you
Thank you
