I put in another pressure sensor and the black smoke is gone and it seems zippier than before. I haven't given it the Texas Street test (A good hill to test these things in central San Diego). An interesting thing. The one I got from the junkyard yesterday had some oil dripping out of it when I took it out of the box this afternoon. Is that a sign of something that was wrong with the car it came from or is it possible that the one I had in there had lost some oil that was supposed to be in there? Now the bad news. It seeks at idle. I suppose I probably have to readjust it with the new pressure sensor. And there is a leak in the fuel lines. It looks like I cracked the one that goes to the #3 injector when attaching the pressure gauge. They all look pretty old and brittle. This brings up a question I have for Jim. You were planning to sell fuel line replacement kits. I think it fell through. If it didn't, I'd like to buy one. If it did, could you send me a shopping list with lengths of what diameter and good brand names.
