It doesnt take long to ruin the engine diluting the oil with gas - i dont know how i dodged that bullet, mine was leaking -gas into the oil- new spider is only the beginning of the care and feeding of the unpowered poppit spider motor- regular bottles of injector cleaner will keep them poppits clean, otherwise fuel deposits mess up the quantity and pattern of the fuel spray quickly from new- i had long suspected the new spider i installed was faulty, (Sorensen), but it was just quickly plugged by fuel deposits-as i understand it, the additives often in gas like to hook up in the poppits- my 1994 4.3 S10 kicks **** now, runs like it did when i bought it 5 yrs. ago, smooth like its supposed to, i was chasing the piggy/miss for two yrs, bottles of injector cleaner didnt help, it needed a heavier mix of cleaner
- it couldnt hardly get itself and a little aluminum boat out of a easy boat ramp, what broke free the deposits was doubling up on the amount of injector cleaner i dumped in the tank, when a person takes a clogged injected vehicle to a shop they hook up a pressurized system to it ,and disable the fuel pump -shop air system is better than aerosol can system, force the engine to run on a <10%> cleaner/gas mix for 20 minutes, guess i did get lucky with results from the cleaner addtive, cuz the real fix is find a shop that does the 10% cleaner 15-20 minute pressure wash of the injectors, and it should be done at least every year- mines running so good now, ill not see a lot of results from the pro cleaning i'm scheduled for tomorrow morning - hate to cancel tho- these unpowered poppits are very finicky - i did reuse my plemun half shell gasket, it has the red rubber line on it and it was still live so i reused it

95% chance its the fuel injector (spider). Take the upper intake manifold off and turn the key on and off a few times and you will see fuel leaking from the spider.

I have a chevy blazer 94 S10 still quit on the road.


How is it running before it quits onyou. This could be the culprit of an egr valve. How many miles on thevehicle. The egr seems to die on a certain mileage pattern. Also youcould start by cleaning the egr valve before replacing it. This couldvery well help the situation, but this is just a guess. Hope thishelps!!

My 94 s10 4.3 vortec was running very rough


Hello;
Make sure the distributor wires are hooked up and making a goodconnection at the base of the distributor. Also make sure the coil wire is fully in the socket. Make sure no wires got pinched for the relays. Hope this helps;

My 94 s10 4.3 vortec was running very rough


I hope this helps, I have had this problem 1 other time.
The EGR valve you bought was a negative and it calls for a positive. Or visa/ verse. If that is the case, it will not start. There are 2 different EGR's for 1994, CFI & TBI, both are the type of injection and are not interchangable on the EGR valves.

Rough idling sluggish acceleration


These 4.3L W motors are common for fuel leaking inside the plenum causing them to run rough and smell like raw fuel. The fuel pressure regulator leaks internally, also the injector spider leaks and the two fuel lines feeding the fuel to the spider. You have to remove the plenum and look for the clean spot. Where the fuel leaks it cleans the oil off. Before you try this check your EGR valve. The EGR valves on these get stuck open with carbon and cause a rough idle. Remove it and look for the plunger it is a small round piece that you can push in and out, make sure it closes fully. You can also clean it with carb clean and they make a replacement gasket with a screen in it to keep chunks out of it. Start with the EGR because it is easier. The parts for under the plenum are available at most any parts store. If you have any problems just ask, and if you can not find the parts I will give you part numbers. Let me know what you find I will be back tomorrow.

1994 chevy blazer 4.3l feels like miss at idle only new cpi,egr,ignition.no vac leaks comp good tsb 4 crank sensor w/ spacer shim?


Just some quick checks: I'll assume you haven't received any error codes.
fuel filter,bad gas(water in the gas), indication of failing fuel pump(the 4.3 is notorious for its pump problems),dirty spark plugs, clogged fuel injectors, failed fuel injectors, MAF malfuntion(mass airflow sensor), I could go on...
