Hey all, finally got around to turning a wrench on my new '99. I did the extra u-bolt mod to the leafs, they went about 3 or 4" in front of the rear axle. I haven't driven it much since then, but no axle wrap so far. If the clunk in first gear was actually axle wrap, that is. But for $11, it's a pretty cheap test. So far so good. While I was under there, I cleaned and lubed the 5 zerks that I saw on the axle.
I also got a can of MAF cleaner and hosed it down pretty well, and installed a new set of NGK V-power plugs and wires. I got a new PCV, but I was trying to finish up quick, and didn't really see how that comes out. It's apparently not threaded, but I couldn't pull the valve out of the cover for anything. The plugs were pregapped to .032", as I have read before and they looked up the gap on their computer - they confirmed .032" as the correct gap for the 2.7L. The plugs went in ok, and I couldn't find my in/lb torque wrench so I used the big ft/lb wrench which only goes down to 20. The wires were kind of a bitch to click into place though; I had to tap them a bit to get them to seat all the way.
First time I started it up, of course it was cold, but it seemed to idle pretty high, and the garage smelled of gas pretty strong. (Yes the door was open.) It didn't sound like it was missing, so I just shut down and had to get to other things. I drove the truck today just a few miles, and the engine seems to be idling really low compared to before. Like 600 rpms or so, sitting at the stoplight, in Drive. I could feel the steering wheel vibrating more than I recall. I haven't had the truck a month yet, so I'm not all that used to it. I'm not sure if it's running better than before; I assume so. My first two tanks of gas got me a 20mpg average city and highway, so maybe in another week or so I will fill up and see if there is any difference.
One thing that had me scratching my head was that intake tube. How the heck does it come off? I undid the pipe clamps, but I seem to be missing some other attachment point. I would have liked to clean the TB, but it wasn't that big of a deal, and I was under some time constraints anyway. Maybe if somebody can point out the obvious bolt or whatever that I missed, I can check out the TB later. Thanks.
