    Hey I have a '94 S-10 with about 145,000 miles. I have had little to no problems with it after i replaced the alternator at around 100,000. Lately when i start the truck it will either idle at 500rpm, idle at the normal 800-1000 rpm, or just fly at 3000rpm. I checked for disconnected vaccuum lines and found nothing. If anyone has any ideas or has had this problem i would greatly appreciate some advice. Thanks
  • Headlight high beam is burnt out. Replace the whole headlight.
  • Hey ya'll,

    Just bought a 92' Chevy S-10 the other day and have been doing a few repairs here and there, but I have run into a few problems and was hoping maybe you guy might have some ideas! First of all, I hear it is a common problem with the digital dash, but everything but the odometer and speedometer is out. I have no Tachometer, no fuel gauge, nothing for the battery, nothing for the engine or oil...I took the dash display out and checked all the bulbs and they seem to be working just fine, but they have nothing to do with the other displays so I have learned. I checked the fuses, nothing wrong there otherwise the whole display would be out. So I am not sure if it is the display or if it is the engines computer or what? I use to have a problem with a squeeling noise while accelerating and taking the foot off the gas, but I replaced the U-Joints and it was just those. But shifting is a bit rough, and it doesnt want to go into first, second, and reverse too easily. I dont know if that is the clutch or the transmission, cause i push the clutch in all the way and it sometimes grinds going into reverse while the clutch pedal is still down. I dont know much about transmissions yet, so I dont know if it is clutch fluid, the clutch or what? So any help with these problems is greatly appreciated! Thank you all in advance!

    Sorry for such a silly question. I have a 99 Sonoma V6 and I thought I'd start doing my own oil changes. I have the Hayes manual which doesn't tell me where the oil filter is. I've been under with a flashlight but still I don't see it. I have the skidplates option, do I need to get under those?

    Thanks in advance, Rob. :)

    I have a 92 4.3Z that I traded from Dad. He bought it 10 yrs ago with 30k on it. Every since day one it has had a high idle especially after start up. He took it back to the dealer and was told that it was normal. He and I searched for vacuum leaks to no avail. A couple of months ago I was changing the thermostat. In the process I discovered that the plastic elbow that taps into the throttle body and goes to the PVC hose was cracked on the bottom. I replaced it and the idle has been beautiful every since. We surmised that it was that way off the assembly line.

    Some earlier 4.3's have an oil filter access door in the skid plate. Looks like this:

    Hi,

    Good Catch - and it sounds like it fixed your problem..

    A couple comments if I may ??

    As far it it being there since day one ?? If it was as noticeable as you say since day one - I 'd have to say the dealer should have easily caught that with a vacuum gauge which logically they must of tried for an Idle issue ... But, you never know ....

    Also, for the original poster / issue - my 2002 does start and idle high for a few minutes AND the clutch in the fan is on as well - so it sounds loud and sound like it is racing much faster than it is ... This is normal .. just for reference ....

    I turn on the ign and no fuel pressure. I hooked up 12v batt to the wires from the tank and still no sound from pump. :confuse: Truck just stopped running.I thought @first it was vapor lock. Put fuel in throttle body and ran until fuel was dry. :confuse:
  • Hello,

    Your post was from June-6, did you get this problem fixed?
    I am having the exact same problem and was wondering if you have a fix for it yet..

    Thank You

    All right, I answered my own question and fixed it. The problem is the fuel pump. It was nice to have a 4" lift, didn't have to remove the tank. :P

    Truck has approx. 72,000 miles on it. 5-6 months ago started losing power going up hills & after driving for long distance. Doesn't matter if AC is on or not. Pretty much had to floor it to get up to speed on the interstate. Going up hills it's REALLY bad. Replaced spark plugs, air filter, ignition rotor, fuel filter so far. Still does it. Plus when I start it up in 1st & 2nd gears it kinda "chugs" and jerks back & forth like it's about to die. Any ideas on what to do next? Check engine light came on a few days ago, mechanic said it was the Max Air Flow Sensor - what the heck is that and WHERE is that?

    I have a broken tailgate cable on my S-10 2001. I want to know what you have found out about this problem. I am new to this forum and just spotted your message. I am not even yet sure how to follow a thread on your message if there is one. Will I have to replace the whole latch assembly? (For those who don't know, it appears the cable is riveted to the latch assembly, requiring the rivet to be cut--I think, to replace the cable) Can I install cables from an Autoparts store by cutting the rivet off the latch assembly and bolting a new cable on? Is there a recall? Will my dealer fix this as a warranty repair? I would really appreciate your feedback.

    I have a 1999 Sonoma 3 door stepside with a 2.2L,auto, and 75,000 miles.
    I`ve never had any problems with this truck untill last week.
    I was at a stop light with the AC on, and when I pressed on the accelerator to go the engine lost power and quit running.
    After comeing to a stop the engine started right up and ran just fine.
    The truck ran fine, and I thought everything was cool----but today I was at the same stop light and the same thing happend again but the AC was turned off.
    I dont know whats going on with the truck, but it kind of reminds we of the old vapor lock thing back in the 1950s and 60s.
    Any feedback would be appreciated. Thanks jjj4

    Christopher, I have the same problem, just went to a junkyard and got a whole assembly replacement and let me tell you getting that thing out is a bear. It was so bad that I don't even want to attempt to do it on my own vehicle. Have you heard of any recalls or easy way to replace the cable? Drilling out the rivet looks like the easiest thing to do. let me know what you found out. thanks......

  • i have a 4.3 sonoma and when i crank it up seconds after it fires it clunks or knocks cant tell ... but it causes the motor to shake briefly :( any ideas???

    Hey, got '04 S-10 (crew cab) 4x4, auto, 4.3L, 21,000 miles. This is my 4th S-10 since 1984 (two good ones, one lemon, and this one which jury still out). Anyway getting a continuous ringing sound @ 2500RPM or so in each gear. Took it in under warranty, test drive and mechanic said probably trany. Appointment and tranny mechanic didn't hear it, second test drive and he heard it, said not trany but part of drive train! Goodwrench doesn't think warrants any further work as there are no bulletins on such a problem. But I'm really concerned I'll breakdown pulling my pop-up camper (about 2000lbs) in next couple weeks somewhere out in the boondocks - where I like to camp with family. So anyone got any similar problems or suggestions???
  • Hey i got a 2001 4WD Chev S-10, Z-R2, great truck 4.3 V6, 46000 miles on it. Runs great and everything, the only thing is i get around 220 miles to a tank. What is anybody else getting, i want to compare numbers with others. Also someone that had a 92 GMC with the 4.3 4WD told me that they started using K&N air filters instead of your standard filter, and they put a flowmaster exhaust system with the medium pipe (thats all you need with the 4.3 V6 anyhow) and it helped with HP and felt quicker of course but said they started getting around 360 miles to a tank! Any Input, or comments about this?

    Another thing whenever i fill up, my gauge doesnt read completely full and judging from only 220 miles to a tank its probably about a 15 gallon tank, right? I heard though these trucks have about a 2 gallon reserve tank so i dont know what to think. Would that 2 gallons be the remaining fuel left when your low fuel light comes on?

    Please tell me everything you know bout these trucks, any answers to my questions will help

    Thanks - Brian

    I beg to differ and are offended by your comment. My S-10 has been flawless thus far; it was just a problem with that particular truck.

    Trucks with 4 bangers are BAD ideas. That is my thought.

    We have the 2002 4WD Chevy S-10, Z-R2, no quite so great truck 4.3 V6, 85000. We use a K&N air filter but have no modifications. In order to figure out my fuel economy I take the amount of miles on the tach and divide it by the gallons of gas I just put in and then reset the tach. We get typically 15-16 mpg. Roughly 250-270 depending on when I stop and refill. The longest I have ever gone with the fuel light on was 17 miles and I think I put close to 17 gallons in the that time.

    29 miles to a gallon is bad, the 4.3 owners are screaming about poor fuel mileage. :)
  • jae5jae5 Posts: 1,205
    360 miles to the thank is great, how they do that?. Have '99, 4.3, 4L60E, ZQ8 suspension. As with chevy02, I usually average 250 - 260 a tank, but have gotten as low as 230. The 3.42 gear my vehicle has isn't the greatest for gas mileage, but if that was my biggest concern I wouldn't have bought a truck. Anyway, believe the tank is 19 gallons, maybe be 18. When I fill up, after the auto shut-off of the pump, I can usually get another gallon into the tank. I've driven about 20 miles with the fuel light coming on and off, but wouldn't make that a practice as fuel pump damage can occur. Just nice to know approx. how far I can go until dead empty. From my experience with GM vehicles, there is usually anywhere from 2 - 4 gallons left in the tank when the light first comes on. My 66 Impala, on the other hand, when it hits the 1/4 mark, I start looking for a station and at the 1/8 mark, I'm in the station.

    Have installed a K&N air cleaner, helped a little in seat-of-the-pants feel, haven't dynoed the truck so don't know how much gain I've gotten. Have been looking for an exhaust, but many don't have an application for my vehicle due to the lowered suspension and rear sway bar.
  • Yeah see im kinda mad cuase im only getting like 220 max to my tank, so i love the truck and all its just that im gonna try and do what ever i can to increase my fuel life. So im lookin into the flowmaster exhaust system a little, more so cuase i love the sound, but im also gonna start using k&n or possibly look into an air intake kit as well. I dont know, suppose i should pay off the truck first! Hah

    thanks,
    Brian

    My gas gage shows full most of the time. I have turn the key on and off a few times to get an actural reading. My 2000 Astro just started doing the same thing.
    I now know why their is a trip meter on the trucks. I fill up every 400 miles on 19 gal tank Does anyone know why it does that and how to repair it.

    I have a 92 s-10 blazer that the piston was stuck out in the caliper hanging up the wheel. I went and purchased a new one and installed it and bled the brake system. Put it back together to find that I have the same problem with the new caliper. Any suggestions to what I may have missed? Thanks in advance

    Hello

    I have 1999 chevy silverado with the same problem :cry: , manual brakes work well but the abs system stop working long ago. don't know what causes this. just waiting on someone on the web to come up with a solution. if i find out anything i will post it here.

    thanks

    A flex hose collapsed internally will act as a one way check valve. Fluid can get into the caliper but not out.
