Hello. My first time posting here. 1993 YJ. 2.5 L 4 Cyl...

I just replaced my Exhaust manifold (and gasket). I got it on then had really high idle. (I read earlier about someone having the same issue). I installed new bolts and hardware and I think I got it. No more High idle.

This is where I have a different issue. It starts fine, but when it gets a little warm it has a idle issue. Goes from 2.5 to just over 3 and flutters in there. Runs, good for a bit, then seems like it builds pressure then loses it. Almost seems like timing. Under throttle, power is jumpy.

I also made my own intake but, I don't have the PCV hose connected. Vacuum?

Thanks!

Trying to figure out my next step...
