If the stock wires are still in there, then just replace them one at a time. The plug boots for the front two plugs are straight and the rest should be 90*. This is to get around the heat shield from the exhaust manifold. If your plug boots don't fit but you have Very high temp compatible replacement wires, then you can remove the heat shield to fit the boots. Be sure that no other wires will be seriously affected.If you have boots that don't fit and probably won't withstand the heat, then you need a new set of wires. If you have trouble getting to the boots to pull them off from the open hood area, then go through the flap in the wheel well for an easier removal.

4.3? Follow the spark plug wires from the spark plugs, they will lead you right to the distributor.

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.

One at a time so as not to mess up the firing order.

A 4WD on a 2001 Chevy S10 Blazer does not work properly after changing its actuator and speed sensor probably due to shorted wires. Also check for loose wiring.รŠ

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.

Sounds like it is need of a complete tune up including spark plugs, spark plug wires, distributor cap, rotor, air and fuel filters.

plug all wires together.

Sounds like it is time for a good tune up including spark plug wires.

The 1988 Chevy Cavalier spark plug wires are quite easy to remove. The spark plug wires simply pull off on each end. Put the new spark light wires on by pushing downward on each end.

Distributor cap, rotor, plug wires or spark plugs could do that. Time for a tune up.

User Avatar

Assuming this is the 4.3L engine, the distributor cap would be found in the back of the engine on top. All the spark plug wires lead to it.

how do you put spark wires in the right place on the coil pack on a 1995 Chevy cavalier2.2 frank

User Avatar

It might but you may also have bad spark plugs/plug too. A bad distributor cap can cause it to miss too.

17mpg - 22mpg, depending on how the vehicle is being maintained. (Air filter, fuel filter, spark plugs & wires, accleration) all the usual things.

User Avatar

If the distributor cap, rotor, ignition wires and spark plugs check okay then I would suspect a faulty fuel injector.

To much resistance in the spark plug wires, replace the spark plug wires.

The spark plugs for any Chevy cobalt are located under the 4 wires that go into the center top of the motor, each one is evenly spread out into a line. Unplug those wires and below them are the spark plugs
