Alright I’m new to the forum. Got this Jeep a few months ago. Several things I want to go through here. I put a new head on recently. It ran great for a while. Then it started to die once it warmed up to 195. And cranks and cranks without starting. It will start once it cools. Here is what I’ve noticed so far. I have an evap line that goes from the passenger side firewall that goes to somewhere to the rear of the Jeep I assume. I’ve replaced the crank sensor several times. Put a new cam sensor on. Throttle position sensor. New spark plugs. When it does run after sitting all night it runs great but 15-20 minutes later it shakes bad and the dies. Any idea what you think it might be. Thanks!
