My wife was driving home when the van started losing power. When I hooked a scan tool, it stated #2 cylinder was missing. Fortunately, it was an easy fix. Took off the top cover, found#2 coil, and disconnected the wire. I noticed no power drop while engine was running. Bought a new coil on plug , and replaced it. Viola, it was fixed. Hope this helps others who may experience this problem. Anyone with basic mechanic experience will have no problem. Good luck.
