#356 of 374 Spark Plug Issue... by the_big_al Jun 27, 2008 (3:16 pm)
So it's been awhile since I have been here and needed to post something, but here goes. I am a bit baffled by this odd bit. Just tonight I replaced plugs, wires, cap and rotor on my '01 4.3 V6 S-10. Everything seemed to go according to plan and there didn't seem to be any major issues - other than fighting the steering rod on the driver's side and the dipstick tube on the passenger side. When I went to fire it up though, it fired just fine, the engine sounded normal, if not smoother than before, but there was a wierd clacking like noise coming from the distributer cap and rotor.   I shut the truck off, took the cap off and looked at the new roter. It appeared that some of top parts had broken off, but I didn't see any plastic parts or debris anywhere in the cap or under the rotor. The broken of pieces didn't appear to be affecting the performance and after comparing it to the old rotor I determined that there wasn't really anything wrong with it. I looked at the cap and it also looked fine. I put it back together and took it for a test drive. It still clacked-kind of like plastic hitting plastic sound. The truck ran normally. No mis-fires, good power, nothing out of the ordinary except the clacking sound.   I got back home and exchanged the new rotor for the old one and I got the same noise. I am stumped. I checked the wiring to make sure I had wired the new plugs correctly and I had. I also checked to make sure the cap was on tight and it was, except that if I forced the cap back towards the drivers side of the firewall the noise seemed to lessen and when I put my hand on the cap, it felt like the rotor was striking the side of the cap... Do I have a bum cap? Or is it something else? Since it was almost 9 PM before I was decided to quit fiddling with the thing, the auto parts store where I bought the cap was closed. Actually it closed about 45 minutes after I bought the stuff so I was out of luck almost before I started working...   So as of right now I am stuck with what to do. I will take the cap back tomorrow and see if they will exchange it - maybe take the guy outside and have him listen to the vehicle... I hope they can do something if it is the cap. It was almost $50... But if anyone has any ideas I am open to them... I just didn't think a simple plug and wire change would turn into such a battle.
#357 of 374 Heating Problem by gerry66 Dec 01, 2008 (4:40 pm)
I have an 02 Chev S-10 4.3L. I gradually started losing heat. Replaced the thermostat with an OEM, flushed the radiator, engine and heater core, bled the system several times, got some heat for a short time, now I have very little heat. I wonder if there is a thermal control valve in this system? Inlet hose to the heater is hot and the outlet is cold. Any thoughts or suggestions would be appreciated.

#359 of 374 03 Sonoma transfer case problem by Indian4Rider Dec 05, 2008 (11:48 am)
03 Sonoma ext. cab, automatic trans w/3 button electronic transfer case; owned since new: All 3 buttons light when key is turned to start; 2WD button is lit once started. NOTHING happens when 4HI or 4LO button is pushed. Fuses under hood and in kick panel are good. Another site said probably bad actuator motor but I couldn't follow up and find out how to check it. Where is this actuator motor? Is there also a relay that could be bad? TIA Replies to this message: Indian4Rider (Dec 05, 2008 1:27 pm)

Replying to: Indian4Rider (Dec 05, 2008 11:48 am) Follow-up: Located and tested actuator motor under battery tray; tested fine w/Mighty-Vac - held steady for over 30 sec with zero vacuum drop. Also determined that there is 12V at the pigtail (switch?) where the cable from the actuator enters the transfer case. Took it out on the road and still no joy. With the truck in "D" moving fwd at idle as per owners' manual, NOTHING happens when the 4HI button is pushed - no click, clunk, hiss or anything I could hear. Looks like the truck's got to be on a lift to check vacuum at the actuator with the battery in place.   There must be a switching valve and maybe a relay somewhere to control the vacuum to the actuator. Anybody know where the clever folks at GM hid it?   Eager for suggestions...

#363 of 374 Need Help on Replacement Shocks: 1999 S-10 w/ ZQ8 by jae5 Feb 26, 2009 (5:12 am)
Good day everyone,   I am looking to replace the shocks on my rig. It's a '99 S-10 (4.3L, auto, reg. cab-short bed) with ZQ8 suspension package. I was wondering if anyone here replaced their shocks on their ZQ8-suspended truck and if so:   Which shocks did you use Where did you get them Cost   I've checked a couple of places like Rock Auto, Edelbrock, Summit (gateway from the Edelbrock site) and GMPartsDirect but it they are hella-expensive (especially if I go with the AC Delco replacements ).   Also, was wondering if anyone has replaced the oil cooler lines and if so:   How difficult of a job was it Any special tools / tricks & tips needed Specific steps / procedures needed to be followed Am I better off taking the truck in to have it done   Thanks everyone   JAE Replies to this message: jpf (Mar 23, 2009 5:37 pm)
#364 of 374 Cruise Control by gabhanjacisa Mar 16, 2009 (6:24 am)
1989 Chevrolet S-10 Blazer 4x4 (originally 4.3 replaced by a 2.8). The cruise control used to work intermittently, it would stay on for a few miles, then shut off, then I could get it back on, etc., etc. Had the turn signal switch replaced last year by a very good mechanic, however the cruise control has not worked at all since then. So, where do I start and what do I do and what am I looking for? Any help is appreciated. I know a little about cars, enough to make me dangerous, I guess. On a scale of 1-10, how hard would this be for me to get into and possibly fix without screwing things up. And, I am not interested at all in removing the cover to the steering column and getting inside there. Thanks, Jeff
#365 of 374 S10-won't run on its own by me1237 Mar 22, 2009 (6:41 am)
I have a1996 chevy s-10 4 cylinder pickup. I went to start it the other day and it started right up but to keep it running you have to keep your foot on gas. The minute you let up it dies. It won't idle in neutral. I was hoping someone might have a clue as to what the problem is or where I should start looking. Thank you.
