We've been checking the wires with a voltmeter, and haven't found anything showing bad yet, but I found a post where they talked about checking all the fuses and stuff too, so I can study up on that and give it a try. I took it to an "electrical specialist" I was referred to, and he couldn't find anything wrong. Yet I get the warnings. So I keep going back to the computer in my mind.
What repair manual would you recommend to help me find these parts so I can test them? PCM, etc., I'm stepping way out of my comfort zone at this point, but I feel I need to try and understand the problem better, maybe I'm giving incomplete information to the mechanics, which is hindering their efforts.
I'll see what I can figure out on the vacuum leak as well. I've read tons about this, but haven't tried much because again it's out of my league. But perhaps with a good manual showing me where to poke and prod, I might have some luck.
One other quick question I have about the computer... There's more than one right? Like a main one, one for auxiliary systems, etc., isn't there? I mean, if it's a bad computer, I have to figure out which computer is bad right? Or is there just one?
I see lots of them on eBay, like this one:

But they all look different, so I"m not sure what I"m looking at. I just wonder if it's worth $80 to try it out, or if its' even something a guy can just swap out like that. Anybody have thoughts on that?
