Thank you for taking a look at my posts, Eric. Unfortunately, I have to agree with you that a problem like this, that has only happened twice in 6 months, will be extremely difficult to find. I will review the videos you suggested and we’ll just have to continue driving the vehicle and see what happens! Thanks again, keep up the good work, and Stay Dirty!

Have you worked through the wiring diagram on this? Sounds like a bad connection somewhere along the way.

I’m just a beginner here but I don’t think the EGR valve should be leaking smoke by as you described. My understanding is that the EGR valve is opened by vacuum acting on its diaphragm so if smoke is coming out thru the valve, either its diaphragm is busted or the valve itself is not closed … like it should be when the engine is not sending a vacuum signal telling it to open. Hope this helps!

Here’s the file I was trying to upload:

We were driving along on a secondary road, about 25 miles from home and going about 50-55mph, when suddenly, the car started riding very roughly and it sounded and felt like we were running over a rumble strip. This noise and vibration sounded like it was coming from the rear end and it kept coming and going for about another mile or two while we looked for a good place to get off the road. When we stopped, I checked the tires (no low air pressure signal) and the brakes (not hot) and everything seemed ok. It did feel as though the engine was idling a little roughly; not too bad, but not quite as smoothly as normal.
We turned around and started home. As we continued on, the noise and vibration got worse at first, but then gradually, the symptoms went away. By the time we got back to the interstate, about 11 miles later, they had disappeared completely. We got on the interstate and came home at normal interstate speed.
We never got a check engine light and the car idled smoothly when we got home. As a first step, our neighbor ran his scan tool on the car for us, but no codes showed up.
This exact same thing happened to the car once before. It was last September; 6 months ago. Same symptoms, etc. We made it home then, just like this time, with the car getting better and better as we drove along. Since then, it has been running fine…. Until today.Here’s the file I was trying to upload:
