My '94 S10 pickup has 136k by golf520

I'm curious about how many more miles I can expect before I have issues? I am having Racaro Seats installed because the standard seats were uncomfortable for long hauls. I thought about a new truck, but like the looks of my truck, it has served me well AND it is paid for, so a no brainer for me! Now I am excited about customizing. We recently put in a Rhino bed liner and sound system...any more ideas? How about maintenance??? Last major 125k and I do oil changes every3k.
 
I'm a babyboomer female that loves to garden and golf...I am also happily married, so I'm only interested in S10 conversations - not pickup!

I got a '93 Blazer with 166k miles. It has been running very well until recently when it started idling at 3500-4500 rpms. It had the fuel injectors and ICM changed. Please help.

Idles up and down and sputters on acceleration by cptspaulding
Apr 13, 2005 (6:22 am)

I have a 89 S10 Blazer 4X4. I changed the fuel pump because of low pressure and fine now. I changed the throttle body gasket. I get codes for all sensors and some that don't exist. fixed 2 computer wires and also replaced computer. It idles at 1000 and immediatly drops to 500 w/check engine light on and immediately idles back up w/light off. This is continuous. I accelerate and it sputters and have to press the gas repetitively and then finally goes. When it drops below 2000 you have to do it again. After about 15-20 min it may straighten out and be fine and then it will do it again when it's cold. Sometimes it will just start again when it's warm. It acts like a Mass Air Flow sensor but I can't find it nor do any parts stores list one. I am about to try the Idle Air Control Valve. Any suggestions?? Thanks

Its not the AC water pipes being clogged. There is air in your water system. Pl flush the old cooalnt specially when the Dexcool is inside it. Replace it with any Green Coolant available in the market. Also take out the thermostate valve out when you are flushing the water out of your system. Once you are funished remember to keep the raditor reserviour bootle full. Last of all if your truck is still with the original GM raditor cap, change it with any good raditor cap. the origianl cap has got the capacity to take air, thus resulting in guggling sound from the passenger side of the truck.
Try it up and keep us posted. Best of luck

Throttle body diaphram spring by kolt45
Apr 20, 2005 (6:42 pm)

the other day i took my tbu apart tring to find out why my 1989 4.3l v6 was flooding itself and stalling out on me, i think i figured out the problems.
 
1. the injectors were spilling fuel even when the vehicle was turned off.
2. when i opened the throttle body, the diaphram spring whas completely broken in half, this creates a problem, because when the diaphram doesnt have a spring, the truck wont run at the correct fuel pressre.
 
the real reason i posted on this forum is because i was curious as to where i would find this spring. is it a dealer part, because napa doesnt carry it, and it doesnt come in the tbu repair kit. any info would be extremely helpful

Whinning noise in front end of 4x4 by chevbear

Hi,
I have a 99 Chevy S-10 Blazer 4x4. I'm getting a loud humming or whinning noise coming from the front end. I thought it was coming from the engine, but when I stop and put it in neutral it goes away. Its only when i'm in gear. I just had the electrical switch that switches from 2x4 to 4x4 replaced. Any Ideas what the noise is. I'm thinking its something with the drive shaft or 4x4. It makes the same sound weather its in 2x4 or 4x4.

Spark Plug Wires by terryalston
Apr 25, 2005 (7:43 am)
Reply
I recently had to remove the head from my 97 S-10 2.2 Pick up because of stripped out spark plug holes. We were able to retap the the threads and do some major cleaning. After putting all back together we have run into a misfire issue. The truck runs great at driving speeds but the idle is all wrong. Though we were cautious when removing and replacing the spark plug wires, I am afraid that one may be crossed. Does anyone know a place on the net that I can find the spark plug wire routing for this truck. Any help would be greatly appreciated.

93 S-10 Blazer Transmission help! I just replaced the motor in my 1993 chevy s-10 blazer 4x4 with the 4.3L Vortec ( threw a piston thru old oil pan) when i removed everything the transmission was running GREAT! My only problem, obviously, was the engine was blown... well... since i put it all back together the Motor is running great! but it seems my transmission does not want to shift into overdrive! anyone know what this is? Do i need to have my truck hooked to a diagnostic computer to reset anything? After i put the motor in, I did start the truck without the transmission in it. All I did to the transmission was change the transmission filter. I believe the transmission I have has the electronic "kick-down" It has a electrical connection on the passenger side of the transmission (i am not sure which one this transmission is) I will post a pic of the connector. CAN ANYONE HELP? PLEASE!!!!! I am moving to West Virginia soon and it is a long drive to make going 50mph cause it wont shift into overdrive!
 
Anyway... here is the pic of the connection (if it works) or msg me and i will email it to you)

I think I have the same problem with some differences. It also appears that others in this forum have some of the same problems. My 1995 S-10 has 176k on it an about three weeks ago it started to sput like low fuel but I had 3/4 of a tank. Trying to keep driving it started to heavy duty stall and then back fire through the pipe. Re-starting it, I thought it would shake the truck apart with back fires and rough running. I thought it was a major problem and stopped and called the tow truck. After about an hour, I helped the tow truck guy and drove it part way up the ramp. This surprised me that it would move at all and it was smooth running. At the dealer they could not find a problem and it ran fine. The mechanic drove it all day with no problems showing up and no error codes. It has been running fine now for the three weeks, about 500 miles. Then yesterday it did it again. Same scenario, started by popping and stalling, a little at first and getting worse. Finally, getting so bad that I had to stop and even afraid to take it into traffic. I let it cool for about 30 mins and it ran but rough. Stopped and let it cool for an hour and it ran all the way home ( approx. 20 miles)(after dark and it was cool) I think I detect a little rough running. I am beginning to think it is heat dependent and it may be one of the computers. I stopped at the local parts place and they pulled up the ignition module that's in the distributor and the main computer. I can replace both for about $400 which is a far cry for what the dealer wants. Am I thinking right here? Does this sound like an answer for some of these other problems in the forum like hard starting and running rough? Which computer is the one that should be replaced?

I just bought a 1988 Chevy S-10 with a 2.5 liter 5 speed. My service engine light is coming on every once in a while when I accelerate. I got to looking at the sensor and all that and I found that the knock sensor's wires are cut and that's why my service engine light is coming on. Can anyone tell me where these wires hook up to?
