SOURCE: Honda Accord one cylinder not firing

The cylinder is not getting fuel, spark or compression. You have already checked for spark on that cable and it appears to be good. Pull the spark plug and see if it is damaged. You can also switch spark plug and cable to another cylinder and see if the miss travels with the plug and or cable. If so, you'll know its the spark plug/cable that is bad.

You can check for fuel by listening to the fuel injector to see if it clicks. Use an automotive stethoscope or a long screwdriver--put the metal end of the screwdriver on the injector and the other end against your ear and listen to the injector while the engine is cranking or running. You should hear it click for each time it pulses fuel.

If both fuel and spark are good, then you are probably missing compression in that cylinder. You (or a mechanic) will need to pull all the spark plugs and do a engine compression test with a compression test/gage set. Lots of things can lead to poor or zero compression including: broken piston rings, burned/stuck/broken valves, cracked cylinder head or engine block, cracked pistons,etc.

Because one cylinder is "dead", the engine has to work extra hard to start and run against a cylinder that is dragging it down. If you find low/no compression in that cylinder, you will probably have to remove the cylinder head to correct it. A big expensive job. It may be cost effective to replace the whole engine with a rebuilt one.

SOURCE: How do you replace ignition cylinder in 1991 Honda

It is recommended, if you have an automatic transmission, that you change the entire ignition switch assembly(the entire apparatus that goes around the steering column and is held in place by two shear bolts that have to be drilled out and require that you remove the steering wheel, the shields behind it and the instrument panel)
It is recommended that you remove the steering wheel HOWEVER, If you have an SRS (air bags) most manuals will tell you to have the work done by a Honda dealer, because disarming the SRS is a bit involved, and there’s no way for you to test it after you have done the job. If you don’t have air bags just remove the steering wheel and ignore the parts that come later here involving how to do things without removing it.
It is possible to change the ignition key lock on a Honda Accord Automatic, without removing the steering wheel and/or disarming the SRS, IF you are willing to take your time and exercise special effort. Since I have changed the lock myself, without removing the steering wheel, I know it can be done. Also, the entire switch costs a fortune, whereas the lock and keys can usually be had on eBay for around $30.00. If you want to give it a try, continue:
First, take both cables off the battery. Before you do, make sure that your radio isn't one of those anti-theft jobs that needs a code when you hook the battery back up. If you don't have the code, no more radio.
Next, remove the shields behind the steering wheel. There are seven screws in the bottom shield, four threaded and three pointed. Remember where they go. After you have removed them, ease the portion of the bottom shield out from around the key lock, then it will be loose. If you have a tilt-wheel model, you will have to push the lever down (while holding the steering wheel where you want it) and then the shield can be pivoted so that it will come off the lever. Then push the lever back up.
The top shield will pull out from the top position with only minimal easing upward and outward.
After the shields are removed, you will see that the lock is behind the wiper apparatus and that the set screw that holds it in (Philips head) can not be accessed in the normal manner (with the steering wheel removed). Don't give up yet. First, remove the illumination bulb from the plastic shield around the lock itself. Turn the bulb holder about ¼ turn and it should then come out of the housing. Then, remove the plastic shields themselves. There are three of them and they will all come off after you figure out how various plastic parts clip minimally onto the lock. It just takes a bit of working back and forth. When you have the shields off, you are ready to remove the lock itself.
At this point, insert the key into the lock and turn the lock to I. Leave it there.
Two maneuvers that would be very easy if the steering wheel were removed are more difficult this way, but they can be done with slow care and effort. First, the set screw has to be loosened, NOT removed. Using a good pair of needle-nose pliers, you can carefully turn the screw out until the lock will clear it (you can see the inner point of the screw where it blocks the locks removal, so you should be able to see when it no longer will cause such a block). Next, you must push in the pin that is part of the lock itself and comes up in a hole in the casing just a short distance back from the set-screw (you may need a flashlight to see the hole). Now, since you don't have the steering wheel removed, you can't simply push a small philip's head screwdriver into the hole to compress the pin. You will have to use something like an allen wrench (with the 45% angle) of the proper size to fit into the hole and carefully fit the end into the hole while holding the longer end. Even then, you probably won't be able to get enough pressure on the allen wrench to push in the pin unless you carefully insert a flat-bladed screwdriver behind the wrench and lever it into the hole. I know, sounds like you need three hands, but if you are careful, and give yourself plenty of time, it will work.
Once you have the pin compressed, with your fourth hand you can work the lock out of the casing. Okay, sometimes the pin will pop back up and you will have to compress it again, but if you work the lock out as much as possible (just a hair) before compressing the pin, it will tend to catch the pin under the casing so that you can continue with removal.
When you have the lock out, you will find that it still has one wire connected to it by what appears to be a piece of plastic with the screw through it. Remove the screw, then, CAREFULLY pry up the end that the screw goes through and remove the plastic part by moving it slightly in the direction of the screw hole and lifting it up (there is a tiny tab at the other end of the part that fits into the lock, so you will have to put that end in first when you connect the part to the new lock). Okay, get your new lock, making sure that it is the same as your old lock and attach the plastic part and screw in reverse of how you took them off.
Now, with the new lock with key inserted and turned to I, carefully slide it back in to the same position as the old one was when you removed it. It should, perhaps with only a slight amount of pressure, click into place (the pin comes up in the hole). When that is accomplished, you should try the key to see that it turns through it positions easily.
If it does, carefully (using the needle-nose pliers) tighten the set-screw that holds the lock in position. Then replace the three plastic lock shields and put the illumination bulb back in simply by reversing the turn by which you took it out.
At this point, you should hook your battery back up and see it everything works as it should before you go through the trouble of reinstalling the top and bottom shields. Start the car.
If it starts, give it a short test drive to make sure it runs and shifts properly then turn it off, replace the shields and congratulate yourself on having done that which they all said couldn't be done.
I hope that this helps you.

SOURCE: Honda Accord 1994 Rough Idle, often miss cylinder

A check on the spark plugs of the 2nd and 3rd cylinder must tell the story. If you see there is a dirty plug, oil soaked or badly burnt we need to check on the firing and fuel delivery.
First of all check for compression if there is oil smearing, it can be due to weak oil rings or compression rings or a faulty bore in case the engine has clocked a great deal.
Also check the valve settings before the firing - spark intensity of the 2nd and 3rd plugs are confiremed. Check the HT wires to the plugs as you have checked the remaining sections. I hope this must give an indication of the lurking fault.

this a problem ignition timing. Need to reset to manufacturer specification, They imply you need to make a mayor TUNEUP. Pass the scanner/computer for easy diagnostic and fix it. You can have some faulty ignition coil or PCM or BCM or sensor,distributorc4c56f9d-edf0-43e1-9703-e5fa31985ec4.jpg etc

I am working on a 1998 honda accord ex 4 cylinder. it keeps throwing a miss fire code for all cylinders when you get on it at about 60 mph and won't accelerate past this until you let off and hit


Hi there:
First I suggest scanned the ECU. The misfire counter function can help you determine which cylinder is behaving badly. Clearly this is not an option for all people and vehicles though.
NOTE: Even without engine scanners you can identify which cylinder is causing a dead misfire. Carefully disconnect one spark plug at a time. If the cylinder you are disconnecting is operating properly you will hear a change in RPM. If the cylinder you disabled is the bad cylinder you will see no change in engine behavior.

Check your ignition system. There are several steps to this.
- Remove spark plugs and check to see if the electrodes look worn down or contaminated. Check your spark plug gap with a plug gapper to see if the electrode has worn down.
- Use a multimeter to check your spark plug wire resistance. They should read roughly between 2,000 - 12,000 Ohms. What you are really looking for is an open circuit in one of the wires. Bend the wires around and see if you lose continuity.
- Check cap and Rotor. Look for carbon tracking or extremely worn down rotor.
- On newer vehicles with distributeless ignition systems coils are prone to failure. If you know which cylinder is misfiring try swapping that cylinder's ignition coil with another cylinder and see if the misfire moves with it.

If you know your ignition system is operating properly you may want to check compression. You may already have the spark plugs out from your ignition check so it only takes a minute to check engine compression.

Fuel injection Service - The motorvac service works miracles. It is available at most repair facillities. Adding a can of fuel injector cleaner to your fuel tank is not ecnough to clean out a severely plugged injector. The motorvac solvent is much more potent and should only be used with a fuel injection cleaning machine. It is a good place to check with a hard to find misfire.

Vacuum leaks - A vacuum leak will cause a misfire. If the leak is near a certain cylinder that cylinder will misfire. You can try to find a leak by spraying down the engine carefully with carb cleaner. If you spray the location of the leak the RPMs will rise. You can also inject the intake manifold with smoke from a smoke machine and look to see if it leaks out anywhere it is not supposed to.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Make sure your plugs are getting spark. If not, check your starter and your ignition to make sure they are functioning properly.
