Hey Tbird,
Just got back from the weekend. Heres what I've done and the results so far:
Changed plugs and rubber boots but not springs. I noticed that there some sort of cylinder inside the springs on all the first on on the passengers side. I'm not sure what it is and the springs I got didn't have that (nor were they the same length, etc). I'm not really sure what that cylinder is or if its safe to toss and use different springs. So I left them alone. They looked in good shape anyways.
Changed oil.
Changed serpentine belt.
Changed PCV.
Seafoam'd gas and intake. Added through vacuum line, let sit for about 25 minutes then gave it a 25 mile drive. It smoked for about a mile or so and then nothing. Not sure if thats good or bad
Overall, gas mileage didn't seem to change. I think my little automotive computer is wacked though as its claiming my stepdad's truck is getting less than I am. I'm going to keep track of it manually for a bit. I really think I'm getting around 14mpg highway though. Not great but I do have the big tires on it and I've not had a chance to change out hte fuel filter yet.
It does seem to be running smoother and quieter though. Not a major difference but noticeable none-the-less.
So, thats where we stand. Didn't get to the diff change, tranny flush, transfer case or fuel filter yet. And my CD player cartridge won't eject.
