Shop Honda Spark Plug Wires

I drive a 2000 Accord V6 AT with about 108k miles. My check engine light turned on. I took my car to Honda and they told me I needed a new catalytic converter. They never explained why or what code they pulled. I then decided to take my car to Autozone and they told me that it was definitely NOT the converter but it was the spark plug wires. The autozone printout reads "Catalyst effeciency low-bank 1" and that it's either due to "Catalytic converter defective, engine misfire, large vacuum leak, or Engine oil leakage into exhaust-valve guide seals, piston rings". Does anyone have any information on this subject? I just want to know exactly what's defective so I don't have to spend money fixing the wrong thing. TIA

Take it back to you Honda Dealer they are right (Catalyst efficiency low-bank 1) this means your cat
is blocking and robbing you of power and fuel efficacy
But i would like to know what code #/#s you had .

98 Honda civic ex: replaced crank sensor, timing belt, water pump,spark plugs, wires and new distributer still no spark. thinking now it may be the computer.

Was the new distributor complete with a coil and Ignition module?

BEFORE replacing the computer - have a professional technician look at the vehicle, access the PCM for DTC's or at the least the basic troubleshooting for no spark should be performed.

Rare but can you put the dead wire to another cylinder that works and see if the problem follows that wire? Get codes just because you should.


Some spark testers could be put on the distributor end and see if grounding the end towards plug gets a spark. Not quite sure why it would pick on just one guessing you have checked that others work?

I have a 1996 Honda Civic EX. I am having problems with starting it. It does not appear that there is any fire getting to the spark plugs. I have been told that it is the ignition coil. I have replaced the spark plug wires, the roto and distributor cap. The car has approximately 189,000 miles. Any suggestions as to probably causes.

Don't guess at lack of spark - watch it happen. Try starting fluid in throttle body as a test for lack of fuel. Perhaps it has neither and we can go on from what you find,

I have a '93 Honda civic.

What would happen if one was to unplug and replug a spark plug wire out of and back into the distribute cap? That would then result in the engine not starting with no spark.

The ICM, Coil, Spark Plugs, Spark Plug Wires, Distributor Cap, and Rotor have all been replaced.

I can confirm the power is getting to the coil, the rotor is turning, the fuel is getting to the chamber (meaning not Main Relay, fuel filter, or fuel pump), and the ECU is working.

All checks on the distributor, check out. A different distributor was tried and still the same problem.

Any new ideas would be helpful. Thanks

Have you checked injector pulse with a noid light?

I'm not really sure how that relates to no spark, but yes. With the plug out, you can visible see the fuel ejecting from the engine.

Due to a rash of Honda thefts in my city I advised my wife to unplug a spark plug wire when she parked at night. After realizing that it could still run on 3 cylinders I then unplugged the thing with the blue and black/yellow wires (top left in the photo). It ran the next day and then my wife unplugged two spark plug wires and the next day put them back and it hasn't run since then. Using a simple circuit tester with a wire and light bulb I confirmed that there is current coming into the coil at the two screws at the bottom (bottom right in photo) but no current coming from the spring at the top of coil. I'm sure the wires have been put in the same position, I sanded the points and rotor, I took the ignition coil and control module to be tested and they both are fine, all the fuses that I can find are fine. Any suggestions? Please help.

What is the year, model, and engine size of your Honda?
