Default Missfire cylinder 2

Changed spark plugs, wires, moved injectors, bought a new plug, checked resistance in wires, checked injector wire, same code. Is it safe to say the valves are bad?

Im gonna check tomorrow, again. I tried today and i borrowed a gauge and cyl 1 and 2 had nothing. I knew the gauge was wrong at that point. Although i tested it cold. I'll try it warm this time. Im not to familar with these vehicles but are they prone to valve problems. The millage is unknown as i bought this with a spun bearing and replaced out with a " low milage unit"😅😅. 2.3 t5 fwd.

No, it's pretty rare, timing belt system failure, bent valves and damaged head gaskets from overheating are much more common.

Update, Rechecked compression on cly 1 and 2. Getting no reading on either wet or dry. Rechecked timing and marks are dead on. There is no way i have two dead cylinders. The car only has a miss in cylinder 2. Ia also ran a compression gauge in both cylinders individually. Nothing on either. The car shouldntb3be running if this was true. No idea whats going on at this point. Ran great before this. Probably going to swap heads and see whats next.

Something isn't right. Does it run? How does it run? Power level normal or extremely low? No way you go from a simple misfire, to 2 cylinders without compresion to replacing a head. Just doesn't jive.

Its crazy! You get on it moves. Flashing c/e light it moves. Ill swap the head and see whats sup.
I have time to play with it. The power level is somewhat diminished but you could still get around.
