One at a time so as not to mess up the firing order.
It is probably in need of new spark plug wires.
4.3? Follow the spark plug wires from the spark plugs, they will lead you right to the distributor.
You probably mixed up the firing order.
I need to know which is the right length of the spark plug wires are going in to the block?
They are in the heads where the exhaust manifolds are bolted to the heads. The plugs have rubber wires hooked to the ends of them.
see if you are getting spark in your wires. or check for cracks and damage.
Replace the spark plugs and the spark plug wires. Replace the air filter. Replace the oil and oil filter. Replace the fuel filter.
To much resistance in the spark plug wires, replace the spark plug wires.
replace the spark plug wires
replace spark plugs and wires
On the 4.3L V6 the distributor is located in the back of the engine, in the middle. Just follow the spark plug wires and they will lead you to it.
lol. go to a junkyard and find a similar vehicle, open the hood, then take a picture. Next time, maybe you should replace the wires one at a time.
