Question about 1993 Chevrolet S-10 Blazer

1 Answer

I have a low mileage 93 s10 Blazer with 4.3 V6 that sometimes runs smooth while at other times behaves like it has jumped timing,shakes,smokes stalls. Also the break pedal is extremely hard to push do

I had just done a complete tuneup 2 weeks ago and was running great then. I went away on a 2 week road trip and came home to it starting hard, rough running and an extremely hard brake pedal

check for loose or cracked vacuum lines, and/or the rotor. It may not be making consistant contact.

SOURCE: 93' 4.3 chev runs rough at times

Have someone turn the key on while you watch the injectors. If any gas leaks out of the injectors, without cranking on it) replace the o'rings around the injectors.

Check the vacum line to your fuel pressure regulator, the line may have a crack in it or the regulator may be bad.

1991 Ford Thunderbird with a 3.8 V6 Started out running rough cold, like it was missing. Tuned it up, cleaned the injectors and throttle body. Running got more rough and at low idle. Found intake...


I think your car has a 7th injector called a cold start injector. Takes the place of a choke. If it does check n make sure it's working properly. That's all I can think of at this time. Hope it helps. Also sounds like you still have a pretty bad vacuum leak. Listen for hiss at idle. Good luck

I have a 1994 with vortec 4.3 that shakes sometimes


Shakes how? While stopping? Or solely while idle, Engine light on?

If if shakes while stopping you need to check you're wheel hubs and or Suspension ,

Shakes at a light, You may have a bad fuel Injector, Check you're psi in you're fuel pump, A TPS would cause low idle or sometimes high idle, With low idle and a bad motor mount it would shake,

I know theres a few things I'm missing but,.. I have a major Headache atm so I'll get back to you with some more, when i can think better. :)

Hard start, rough idle, some black smoke, engine service light on


A scan for trouble codes may point you in the right direction quickly, rather than hit & miss, with replacing parts. Some of the autoparts stores will scan for free, and your right where you need to be to get the right part at the same time.
