97 850 sedan: can a misfire caused by bad pcv?

Post by CIK7 »

I took a screenshot of my message with someone about their 97-850 that maybe I will buy. I understand a vacuum leak could cause the engine to run rough, but can that really cause a misfire? And can a bad PCV cause a misfire?

It was probably that intake manifold leak that caused the misfire
