Intermittent rough engine and misfires both in idle and while driving, codes P0305 and P0300

Not always smelling it. My daughter was in the back seat when she smelled it but that only happened once. I’ve smelled it up front and also from the back. My buddy was up towards the front. My niece said she smelled like a burnt fuel odor from the exhaust area.

My buddy that helped me do the pump said he did not see any leaks while under the Jeep.

If I smell it, it’s usually when first starting the vehicle. I had just started up when my buddy mentioned that it smells rich. We were driving for a little bit when my daughter smelled something but it’s also possible she smelled something from outside. The smell from the exhaust yesterday the car had been running almost an hour.

So just hooked up the fuel gauge and everything seemed to hold steady.

Key on engine off.

Engine started up and idling, needle shook as rpm was dropping but stayed steady.

After shutting down the engine. And it’s still holding the same pressure a few minutes later.

I have seen video online of and injector failing after it gets hot. Think maybe situation happening here? Seems to always start or get progressively worse with heat.

Just restarted and the fuel pressure went back to right at 58. Although this time when I turned off the fuel pressure is higher than the first time. And holding there now.
It did smell a little rich to me when it was running. Not like raw fuel but definitely can smell something.

Plugs are new. We pulled plugs when we did compression check. They looked okay to me.

There’s some water coming from the tailpipe. I just got it to sputter and held a piece of paper by exhaust. It did suck it in while sputtering.

The pressure held perfect this time. Is the receipt paper getting sucked into the exhaust a valve issue?

So no concerns about some suction from the exhaust pipe? It only happened briefly while a sputter was occurring.
