If the plugs are firing correctly on those cylinders and no fuel is coming out while the plugs are pulled the injectors are the issue, either the wires to them or the injectors themselves. Use a multimeter to test the voltage while running to the injectors to see if they are getting power to open. If they are you have your problem locked down.

What do I do next? My 2001 olds alero 3.4l v6 is misfiring constantly. Scanned obd2 error code p0301. Already changed spark plug, wire, and coil for cylinders 1 and 4. Still have same problem.


I recommend checking all injectors and O rings on the injectors if an O ring cracks air can raise Cain with misses so can injectors another thing is cam to look at will cause a constant miss but only on 1 cylinder at a time but doubt its the cam. check injectors and O rings also pull 1 plug wire at a time with wire pliers while engine is running and find the 1 cylinder that is giving you the problem when you pull the plug wire that is missing the engine will smooth out then that cylinder is your problem wear rubber gloves with the plug wire pliers so you dont get bit let me know if i can help please rate my solution as this is how i earn my achievements on fixYa thanks.

Replacement Spark Plugs Continually Misfiring for Cyl. #1


Locate the ignition coils - they are mounted on the ignition module. Remove the wide connector that goes to the module. You will have to unscrew it first. Spray some WD40 on the connector pins and try to scrub them with a tip of a small screwdriver. Be delicate not to brake or bend anything. Reconnect the connector. Start the engine and see if it still misses.
If it still does, try to touch/move each of the wires that go to the ignition module. BE VERY CAREFUL not to touch any of the moving parts of the engine as you have to do it with engine running.

If it still misses, do the following.
1. Engine off
2. Mark the ignition wires so that you reconnect them later in the same order
3. Locate the coil which gives spark for cyl 1
4. Switch locations of this coil with any of the two remaining coils
5. Reconnect the wires
6. Start the engine

If it now misses on another cylinder, you will have to buy a new coil.

Car idles rough, sometimes dies in reverse, it's worse in cold.


A cylinder that doesn't fire could be 1 of 3 things: no spark, no gas, or no compression.
Sure, it could be a bad injector, or clogged, but you should do some tests before buying an expensive new injector. You should first check the injector circuit on #2 cylinder. It's a pretty simple circuit, really. Each injector has 2 wires, a power wire and a ground wire. The power wire is one wire, which is spliced to each injector, and has battery voltage on it anytime the ignition switch is on or in "run". Each injector's ground wire is a separate wire going into the computer. When the computer internally grounds for a split second that injector's circuit, the injector sprays fuel out a tiny opening, a nozzle. You can check the circuit for #2, both the power wire and the ground side of the circuit with a test light. Post back and ask, if you want me to explain.
You also might want to check the compression in #2, just to assure you there is no mechanical problem causing a loss of compression in that cylinder.

Have 1994 toy. truck with v6, when choke goes off the engine misses


Hey 94 TOY...

When did the problem start? Before you changed the wires and plugs? Or did it start, AFTER you changed the wires and plugs? Did the problem remain the same BEFORE & AFTER you made the changes?

1 - If the TOY ran fair to Okay before you did the work, then you may have done something wrong when you made the cahages. Check for correct plugs and firing order. Check for cross wiring. With engine runing pull one plug wire off each plug one at a time. Each pulled plug wire will slow down the engine. When you pull a plug wire that doesn't react and does not make any change ON or OFF that cylinder Plug.
Then that cylinder is not firing.

2 - Check for spark at that wire. If you do-not have Spark there, But the other wires do... the wire going to that cylinder is BAD.

3 - If you have the correct firing order and spark at all cylinders then the cylinder that did-not change the speed of engine has a compresstion problem. Bad valves, Piston or rings are bad... Major engine work and Major repair bill for the repair job.... GOOD LUCK....

'86 honda accord 4 cyl...runs very rough as though missing on 1 cyl ...when removing plug wires 1 at a time each 1 removed makes engine run worse except for #1 cyl which when removed smooths engine out...


no, the plug is firing. But the timing is off. the plug is firing quite a bit before top dead center on that cylinder. The burning of the fuel mixture is occurring while that piston is on its way up and is slowing it down---dragging down the whole engine. i think you should change the distributor cap and rotor as cylinder one is firing at the same time as cylinder 2or 4. This indicates a possible carbon track in the distributor cap.

2006 dodge caravan, 6 cyl. relaced cole, sparkepugs and wires in oct. 2009. Engine is reading #2 cyl. misfire again. Why


Firts time swap spark plug & ignition coil between two different cylinders and read again if the same #2 cyl. misfires !
If #2 cyl. is OK and another cyl. misfires then spark plug or ignition coil is out of order and must be replaced.
If #2 cyl. misfires again then #2 injector must be checked !
If ignition coils & spark plugs (complete set for 6 cyl.) are replaced then you must check #2 injector !

Getting firing code error for cylinders 1,3 & 5 on my 1999 Sonata


I was wrong about the distributor being round (I was thinking about my other car). I found variations about the firing order but after troubbleshooting, varified the plug wiring order from the front of the car is 1 - 4 - 5 - 2 - 3 - 6 not 1 - 4 - 5 - 2 - 6 - 3 found on several web sites. From the front of the car looking at the engine, the back three cylinders by the firewall going from left to right are 1, 3, 5. The front three are 2, 4 & 6.
