I'm planning on doing a couple of projects on my new Burb this weekend. Any advice is appreciated. Burb is a 99 K1500 with AutoTrac with 180k miles. First I'm tackling the FI/Manifold/TB/IAC/PCV removal, clean and reinstall. Hopefully this will clear up the rough idle issue. I have this manifold gasket set waiting for me at the parts store, but I notice it says does not include manifold bolts. Are there gaskets or O-rings on the manifold bolts that should b replaced as well? I also learned that Fel-Pro had an improved set for my 03 Burb, but so far I haven't seen anything like that for the 99 5.7. Next up is sticky/slow door locks. Plan of attack there is to clean all the linkages and rods in the doors to hopefully free them up. If that doesn't fix them then I'll move on to the relay and actuators. Pointers and tips welcome and appreciated. Happy weekend to everyone!
