A couple of issues have surfaced lately and I figure I'd update the thread to see if there's any ideas to help me out.
The first one is that I did some damage to the truck wheelin' in the backyard. I was driving down a tractor road in the woods with my Yakima bars on, cleared a tree with the truck, but didn't think about the load bars. Sure enough, one caught the tree (more like a sapling), and tweaked the rack, which in turn tweaked the gutters. Now, when it rains, it pours in the floorboards of the truck. Looks like I'll have to clean the gutter sealant, and reseal. I've read the threads, just wondering if anyone has a good way to get the old sealant out. I've got a garage to park the truck in now, and it's not my DD, so it's not been a huge priority, but it's moving up the list.
Another problem I've been having with the truck is it has been idling rough, almost skipping, was weak on power, and getting HORRIBLE (<10 mpg) mileage. Also, the truck was running really rich, and required more than 10 pumps to start when cold.. I was told the truck had a new carb on it, so I was assuming that it was the smog stuff causing a problem. Again, the truck still ran OK, so it wasn't a high priority. I had been researching desmog threads to prepare myself for the chore in the next few months.
Now we've got a short trip (3 hr round trip) that we need to use the Cruiser for, so I spent last night in the garage with the Emissions manual and the Crusier. Turns out I was missing a vacuum hose from the metal spaghetti to the vacuum switch on the fender, the VSV (I think) on the pass side of the motor was in backwards, and the lines running to vacuum advance of the distributor were crossed. I fixed all that, the truck purrs like a kitten, and pulls like it never has while I've owned it.
The only problem now is that it has a bit of a flat spot between 2-3k RPM if you're not flooring it. Wide open, it pulls strong through that RPM range. Partial throttle, it climbs to that range, then gets slower in building RPMS. Over that, it's back to normal. Any ideas what that might be?
After playing with that stuff last night, it's obvious a desmog is still in my future, as the vacuum lines are getting old, the EGR tubes are brittle, and I'm not sure all the different valves are working as they should. But it's running better, which is a start.
