Many things can cause such an issue, but the one issue that is solely S-10 related is that the earlier-model poppet-style fuel injectors used in the '96-and-up model year Vortec engines were prone to sticking open or sticking shut after a large mileage buildup. Gm was even forced to address the issue in the early '00's by updating the injector style. The new injectors had the same flow rate, but were designed in such a way as to alleviate the problems found in the earlier ones. There was even a forced recall/replacement in the state of CA due to a lawsuit by the EPA in that state, claiming the poor design was leading to a higher-than-average rate of emissions testing failures in the above-described model years. This is oftentimes the culprit in the 4.3 engines when all the other standard solutions have been exhausted, ie: spark plugs, wires, cap and rotor, etc...
start with checking the coil packs wires sparkplugs
Check condition of the plugs, could also be coil pack(s) going out, if ignition looks good check compression all cylinders
P0300 is a random cylinder misfire. Ensure engine is properly tuned.
The timing is off. it will need to be hooked up to a hand held computer system at a shop to correct this.
Start with a bad Spark Wire Followd by a new Distributor Cap and Rotor button. Pening that failure, replace the sparks.
Several things can cause your 1996 4.3 liter V-6 engine to misfire and have a vibration. A bad fuel injector is the most common cause.
NO it will not.
A lot depends on when it is sputtering. Is it hesitating under acceleration? That is what happens most commonly in eclipses. It is probably a misfire in one of the cylinders. Change your plugs and wires.
Misfire can be caused by many different types of problems with your valves. It could be burned or leaking valves, carbon build up on the valves, weak or broken valve springs, worn valve guides or lifters, broken worn or bent rocker arms or pushrods, worn camshafts, improper valve timing, or worn pistons or rings. A misfire is basically when the cylinder is not producing enough air-fuel mixture properly, so your valves may not be supplying the proper amount of air into the cylinder, for the compression to be strong enough for combustion.
Where what! What is your question?

It could be out of time. It could be connected to the wrong plug in on the distributor. Check your wires for breaks in them.
