I just got home, but I've got tomorrow off so I'll look at it tomorrow. I'll replace the thermostat and switch out the map sensors from my 87 2.8 s10 and see what happens there. Is the vacuum switch under the battery? If so I've checked that before and it moved freely. Although the 4 wheel drive did quit working last year, but it was just a bad EGR valve and it works fine now. Resetting the timing might be a bigger project, 1) I don't own a timing light and 2) I've never really messed with timing. But I have a couple of friends who work at the chrysler dealership at home so maybe I can persuade them to do it over the holidays. Also if I remember right it was getting bad gas mileage before I changed the thermostat... Thanks for all the help so far.
