I have a new to me 1985 that was running great. Last night it developed a misfire. What has me scratching my head is when pulling the spark plug bootss on the right side of the motor nothing changes. Now unless the Vmax is a diesel and I don't know it, I don't think the misfire is bad enough for two cylinders to be dead. Plus the exhaust do warm up. WTH is going on? What can cause both of the right cylinders to misfire? Thanks!
