Default Broken PCV elbow hose HELP!

Hey folks, So I've seen online that this is a common issue with the taurus!

SAMPLE OF THE EXACT PCV ELBOW I HAVE

The top portion of that part is broken and I have a misfire (might be unrelated), loss of power and some above average vibrations on idle.

Now I bought the car like this a few months back, But I realized this pcv elbow recently, the check engine codes indicate a misfire on cylinder #4 and below threshold efficiency on the catalytic converter.

My questions
-May the broken elbow be related to the symptoms mentioned?
-I read there's a revised, ribbed version available, however online for sale I only find the exact same version of the faulty one that I have (like the ebay link) anyone know the model or a link to purchase the newer one?

Thanks!

The PCV hose is a vacuum leak, and will cause lots of problems, including missfires. Missfires can and will damage the cat. Fix the known problem, reset the PCM (disconnect batt for 10 minutes), drive it for a few days / 100+ miles, and see what codes return. Hopefully the missfire didnt damage the cat.

Pic of revised ell and attached line that goes to the PCV valve.

Available at RockAuto for about $13.50 + S&L. Vacuum leaks do not effect all cylinders equally, and make the engine run lean, mostly at idle and low speeds.

PCV valve replacement is quite important. If that sticks, it makes the engine run the opposite of a leak, and the exhaust that bypasses the rings into the crankcase with it's water, mostly stays in the oil. SLUDGE.
