Mike I have the same problems, very similar, i have a 2002 with 80,000(mostly highway). My gas gage does play around just like yours, it will read half full then 5 minutes later it could ready empty. The 4wd (4hi) is whats really worrying me tho. the same thing also is happening to me, it's not engaging all the time and it seems to be getting worse, meaning it's not engaging at all in 4 hi. I am planning on lifting my truck in 2 months and this is a big deal. If i find anything on the internet about how to solve this i will let you know, but i am going to tear open my transfer case either tomorrow or monday and have a good look at whats going on. i know alot of mechanics and i'm in the field of mechanical engineering. I will get to the bottom of this and let you know. In the mean time ( when u say transfer case control module) thats a computer chip or gears?

chances are , you need new window/door trim . i say this b/c of your phrase "air leak" i know your trim is pretty new, but sometimes things happen, such as winter or leaning against your window and taking it off it's support. find out where the leak is and if it's from the window then it's trim.

Check fuel pressure, check coolant temp sensor.

Engine/pulley/alt. noise.. by joe3891
Mar 20, 2005 (7:27 am)
There has been an issue with the timing chain tenioner on that engine coming apart. Check at the timing chain cover with a hose or wood rod to sound out the noise, if you can duplicate it without driving it.

Both you & the previous post should check your Catylitic Converters. I had this very odd rattle, that started off subtle, but got a little more obnoxious as the months went by. My truck still ran fine all throughout. Usually was more noticeable when running through the gears. Highway speed, idle & foot off the gas all made it go away for that time being too.
 
To check, just roll under your cab, passenger side & locate the big oblong bulb-ish looking piece that is connected to your exhaust, usually just under where your passenger seat is located (but under the truck of course).
 
Just kind of tap it with the palm of your hand (maybe a little harder than tapping, more like a solid trust) and see if that sounds familiar. More than likely the element inside has expired & would be rolling around loose in the metal housing. If you bang it & it's just solid, no rattling at all then it's probably something else.
 
The crappy part is... if you live in California then you can only get an OBD2 compliant replacement which is about $456. No aftermarket alternative on that one. Though you will find them online for $56, $188 or $240 you must read the fine print because they're not OBD2 compliant & not valid in CA. OBD2's are ONLY available at the dealership.

I have an S-10 Ls ext. cab vortec 4.3 4x4 and want to use it for offroading so i was considering lifting my truck as well. Also i want to get some protective skid plates on the bottem to protect the under chase from rocks and etc. Does anyone have experience with offroading with there S-10? if so did it preform well or was it a waste of time?

Kink #559 & Check #490....Looks like there's a few "suckers for a cute S10" out there. I've used my 4WD Hi a few times every week now and had no problems! Every time I went to the Chevy dealer they'd reset the TCCM by unplugging then plugging in the module under the passenger kick panel. Finally, I made them tell me how to reset it and threatened them if they didn't fix it they'd buy the truck back. They reluctantly replaced the encoder motor saying 'it couldn't be the problem, they never go partially bad'. GM called me back a few weeks later to say they didn't forget me, and gave me a 1 year smart care plan for oil changes at this dealer. I feel sooooo much better now. Does anybody need a free oil change? I can't wait to go back and tell them the gas gauge is still messed up. Give this message to your dealer when they say it couldn't be the actual actuator causing the problem.

Now that I have spent way too much time and money replacing a fuel pump in the gas tank all weekend the problem is still there....but I have more information...hopefully somebody can help. There is a new fuel pump, fuel filter, and the fuel pressure is at 58 pounds which is perfect. So, I have narrowed it down to these symptoms. First the truck fires up just fine....then I can rev it up over and over again as if everything is fine...in 3 minutes when the truck is warming up and the idle drops to a normal warm running idle the problems arise...it still idles fine but when I rev it to 1800-2500 rpm the engine starts jumping and dropping off...hesitating and so forth...like starving for fuel or something. Engine shakes really bad when this happens. Could this be the pressure regulator or injectors..? I dont think it is electrical because it only happens when it warms up...I have also read something about having a bad ground but I don't think that is the case here....please somebody help...I am missing work now...which makes it worse. Any ideas.?
