Subject: '93 Dakota with the 3.9 V6 w/165K miles
For about a week I've been getting a very random, single dead miss, usually when sitting at a light, or just as I take my foot off the brake to pull away from the light. After that, accelerating or at steady cruise, I haven't felt a miss.
Tonight, it misfired a bunch of times in a row then went back to usual, except I was hearing a new noise. Investigating while the truck was idling, I found the PCV valve just buzzing away.
Truck feels no different. No loss of power, idles as smooth as before (well, between the random dead miss).
I replaced the plenum a year ago (used the Hughes kit) just after I bought the truck. I also replaced plugs, wires, cap, filters at that time too (about 8K miles).
And its supposed to rain the next two days.
Suggestions? Ideas?
Thanks.
