Hi Dave, we'll investigate the EGR valve. One thing, though, is that this hasn't been an intermittent issue. This came on severely and suddenly. Monday morning, the car drove in its usual great, smooth manner. That afternoon, I started it up, and it was very rough - car shaking rough, along with some pinging. It has not done either of these things before, and the problem has remained, so we're not driving it.
The one thing that was intermittent was the slightly high idle that went away when restarting the car. But, the car wasn't running rough or pinging when that happened, and I don't know if the the slightly high idle was some sort of precursor to what happening Monday afternoon, or if it's completely unrelated.
I've got a set of 95 FSMs on the way, but will look into these other manuals, as well. I have the FSM for the 85, and it's come in handy. I am quite interested in how these cars work. They are not simply transportation, but are very interesting machines, as well, and it seems they're quickly becoming a hobby. I don't have the background, training or tools to do a lot of things myself, but I've been able to successfully do a few things, and I feel good about that. Over time, I'd like to learn more and also obtain some tools to help out, besides the most basic tools.
I will try out the door thing, too. That's pretty cool, and I want to see it in action.
