The 3.4L Chevrolet V6 is very limited to performance up-grades. It was about optimum in performance when it left the factory. The exhaust system is very good and the ignition system is excellent. The S10/S15 Blazer/Jimmy fuel injection system can support up to 300 HP without any modification.
Use a premimum NAPA distributor cap with brass electrodes. The AC Delco distributor cap is equipped with aluminum electrodes which will oxidize and fill the cap with alumium oxide dust which will cause spark scatter, especially with the factory high voltage electronic ignition systems.
#3260 of 3676 1995 GMC Jimmy temperature gauge reading faulty
Aug 24, 2008 (10:59 am)
Hi, I have a 1995 GMC Jimmy. I have replaced the water pump and thermostat due to a percieved overheating problem. I have a snapon mt2500 that I hooked up to the computer. The temperature is running from 185 degrees to about 195 on the scan took. No over heating. It is cooling just as it should. The gauge reads about 250 degrees. Is this a common problem? How can I fix this problem. temp sending unit? or different gauge cluster? Any ideas? Thanks -Ben

The sending unit is more likely the culprit. If you have access to an ohm meter, you can check the resistance of the sending unit. It should read around 2.5K to 5K cold, and below 200-300 ohms hot (170 to 200 degrees).

Last week while driving my 97 Blazer i noticed the volt gauge dip down to about 12 and the running lights went out. It immediately went back up to 14 but the lights never came back on. When i restart it the lights come back on again. I had the alternator replaced even tho it tested fine. The battery also tested fine. It continued to happen about 3 times on my 20 mile drive to work every day for the last week. This morning i started it and was backing down the driveway and it died. It restarted and i got it back up the drive. It died again. Now when i try to start it i dont hear the fuel pump. Are these problems related?

This really sounds like a loose connection. Alternator is 14 volts, battery is 12 volts, so the alternator is going offline when the voltage drops to 12. Could be alternator or battery, or ground. I had a similar situation and it turned out that the hole in the battery for the positive cable bolt was too shallow, so the bolt bottomed out and was not really tight. A washer under the bolt fixed it.
#3264 of 3676 95 GMC Jimmy Suspension & Steering
Sep 10, 2008 (7:52 am)
I am new to the forums and as such don't have much of an idea how it works. I recently bought a 95 GMC Jimmy and have noticed that the truck seems to dart to the left of right when I am driving. There is also quite a bit of play in the steering wheel. I have also noticed that the truck seems to lean to the passenger front side when turn sharp corners. I am wondering if anyone would have a general idea of what could be causing this problem. The truck is in mint condition other than having 314,000 km, but the engine and transmission were re-built at around 170,000 km. I will be taking it into a shop soon, but i don't want to get ripped off, so I though I would ask here first. Thanks, in advance, for your time and help.

Ouch! If a 4WD, probably ball joints. Also should have a close look at the tie rod ends, centerlink, and idler arm. Idler arm, tie rod ends, and center link are easy to change. Ball joints, you need to know what you are doing as the springs are involved and care must be taken to compress them safely during the repair.
#3266 of 3676 2000 Blazer4X4 Trouble
Sep 12, 2008 (4:53 am)
Does anyone have any info as to why my 4X4 comes and goes as it pleases? The lights on the dash blink or go out completely and the truck runs like garbage and now the service engine soon light comes on. It feels like the brake is on until it gets into second gear (auto trans). If I manually shift gears it's not as bad, though (again...auto trans). I've been searching for related issues for 4X4 problems but can't find any. I'm trying to diagnose this myself so I don't have to pay a mechanic a couple hundred bucks just to look at it. Any help would be greatly appreciated.

the anti-theft system is full of bugs. there is only one way to fix it and that's by bypassing the system. however, the only way to do that is by having a remote starter put in. i went through the same thing and replaced the ignition and switch but it still happened. after i put the remote starter in i never had the problem again and that was 2 years ago.

Slop in the steering could be a lot of things, as mentioned. Also, if 4WD the axle hubs and wheel bearings may need to be replaced. Thats a lot of miles, and most people don't lube the front end parts very regularly, so a lot of wear is not suprising. I would go to a front end alignment shop first, preferably non-chain, and have them check the alignment, usually $25 or so. Stick around while they do it, and they can show you where the free-play is. Once you know what is needed, then you can get some estimates on repairs. For parts, I've been using Rock Auto, online store, good prices, quick shipping, usually name brand parts. I don't have any vested interest in the store, just good results. Tie rod ends are less than $10, not too tough to do at home, ball joints less than $20 each, much harder to do at home.
