    YOu may no this but when you run you ac your using more gas! well it should lower your rpms whenyou do have the compressor on. so that may be why!!

    I think the most common answer from the dealer when they don't know why or what. They don't know. Today vehicles have onboard computer that will monitor everything. If your have a voltage fluxuation, it is not right. Check if other items are doing to same thing. if so possible alternator. If not could be bad harness connection at that components. The fact remains its not right. If its under wartity they must fix it.

    There is a device that can be plug into the computer prom. It cost about $135 at Autozone and must have some car smarts, it will monitor 5 or more functions. This small computer plug in and down load on your home computer and can determine what is wrong. but it sounds you might have a cloged fuel filter. does it buck some? Todays engines are computer control. They all have ECM's Engine Control Module.

    It sounds like you have a major fuel system problem. Your line should not be moving. Thats shotty workmenship, take it back , most fuel pump are in the tank which require to drop the tank. If your using bargan gas stop. start using top grade. thats your noise. Have the mechanic check fuel pressure to thottle body ejector. Your S10 has a ECM also the technician can hook up the prom to monitor the fuel system. Use different mechanics for specialize items. For tuff things the dealer shop is sometime best.
  • I HAVE A 99 GMC JIMMY THAT DID THE SAME THING FUEL PUMP WENT OUT THEN NOT TOO LONG AFTER STARTED SPUTTERING AT LIGHTS AND IN DRIVE THRUS. I HAD THREE PLACES CHECK IT OUT AND NOTHING WAS FOUND FOR CERTAIN. SO I PULLED IT APART MY SELF AND FOUND THAT THE BACK THREE CYLINDERS WERE STARTING TO GET WASHED OUT BY EXCESS FUEL. PROBLEM FUEL PRESSURE REGULATOR!!!!!!!!! WHAT A LITLLE PAIN IN THE [non-permissible content removed]. IT IS VERY INEXPENSIVE AND NOT TO TIME CONSUMING TO FIX JUST A FEW OURS OR SO. WHILE YOUR IN THERE FLUSH THE INJECTORS ALSO. THOSE ARE A HUGE PROBLEM ON THESE CARS!!!!!

    Right now, the owner of the company I work for is selling his 'old' 99 S-10 because he bought a new [luxury] car recently. The damn thing only has 27k miles (used to drive to and from work... about 8 miles each way) and the only mainenance needed has been a new alternator... although the driver's side recliner handle snapped off as many people here have had the same problem (how retarded). Anyway, he's willing to sell it for $5500 to me, being as how I'm his employee and I'm just that cool.

    Should I take the deal?

    start with the basic i guess, 99 2.2L 73k, no problems with the damn thing, till now, Something in the motor makes a noise i've never heard and i've worked on motors before, almost sounds like a bearing, it only happends when rpms are about 1k to 2.5k taking off or crusin at 40 and the tranny shifts down to that range. I've changed the belt tentioner 6 monts ago,alt 1 year ago and i need some help please, motor is running fine, sound is comming from from to left side of the engine, Guys if anyone could help that would be great..........thanks for your time............

    1990 chevy s-10 pu has to idle at least a half an hour before drivabilty replaced fule filter, idle air control valuve, pulled gas tank, new sock, cleaned tank operated fule pump manualy pressure past thumb, all seems ok but brake fule lines after an hour of not running no pressure in lines.
  • 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.

    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.

    So should I buy the truck or not?

    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.?

    My axle seal is leaking. I have the crew cab 2.2 5 speed. Anybody else have this problem? Do I have to pull the Diff. cover to remove the axle?
    Thanks, Pete
  • Ok i was told that chevy had 20,000 s10 that have a messed up wiring system. Well mine is one of them. The truck will not idle at anything less that 2800 rpms once the car is warmed up. The code for the throttle positioning censor comes up though it has been replaced a couple times. I have gone though the system and found no shorts but it doesn't mean that there isn't any because if i let the truck sit for a while the battery will be dead. pretty much every sensor has been replaced. If anyone has any ideas please help.

    I have a '88 chevy S-10 2.8. The fuel pump quit on me. I replaced the tank mounted pump but no luck. I got another pump and it ran great when jumped. After installation, it ran fine and the engine ran for about a minute. Now it's dead again. The manual said a bad oil pressure switch would make it inoperable. Replaced that and no luck. Anyone have a solution?
