You may have a bad coil pack - try moving two of them around and see if the misfire follows the coil pack or stays at the same cylinder. If it follows the coil pack, get a new one. If it stays in the same cylinder, inspect your spark plug wires and make sure the plug is gapped correctly.

SOURCE: i cant get spark out of the coil pack

cam sensor fires the injectors to synchronise injector pulsing with the spark at the spark plugs.. U need to probably change the crankshaft sensor (around the crank pulley) as the crank sensor is what controls the ignition spark.
hope that does it.

Engine light flashing whole car shakes and motor sounds like a helacopter..... tested it and it said spark plug 4 misfired........... replaced all 4 spark plugs and it's still reading as a misfired spark...


Sounds like it's either a coil pack or an injector to me, try switching the number four coil pack with any of the other coil packs if the miss follows the coil pack you need to replace that coil pack. if not it's either a fuel injector or a mechanical problem inside the motor, I would rent noid lights from a local auto parts store and look for injector pulse in the cylinder with a misfire, if the noid light is flashing it may be better to leave it to a professional as it is likely internal engine damage. hope that helps. chris

When i start my 2001 kia optima my car putters. i changed my bad o2 sensors. but not sure what the problem is. and when i drive sometimes it jerks. what could the problem be


The spark and fuel system needs to be inspected.--------- The spark plugs are getting fouled or very loose, can cause sputtering problem.Inspect the spark plugs and coil packs.The spark plugs gets power from coil pack.If the spark plugs are very old and dirty, then it needs to be replaced.--------------- The **** problem also relates to faulty worn out spark plugs or clogged fuel filter or low fuel pressure or problem with ignition coil pack.----------- When coil pack stops giving power to spark plug the car will **** while driving.---------- So very first thing you get tested is spark plugs and ignition coil packs.If they are tested good, but looks very dirty/ worn out, that can also be the reason.----------- But if spark plugs and ignition coil tested ok and cleaned properly, but still same problem, then get fuel pressure tested.If fuel pressure is low, the fuel pump and fuel filter are the cause of problem.----------- ------------------ Also one more thing, " IS there check engine light coming ON dash" ? If yes, then get the car scanned at autozone service center.Its absolutely free to get car scanned at autozone.They do it for no charge.------- In scanning you will get error codes, as per error codes, it will point towards faulty part, causing this sputtering and jerking problem.----------------- But if there is no check engine light ion dash, then get the above mentioned possibilities checked.That will help.Thanks.Helpmech.

# 6 misfire while driving start to stutter check engine light flashes then stays on next day light is off and repeat


I am assumming you have a 4.6 V8 in your car. The number six cylinder is on the driverside the second spark plug from the front. These engines have seperate coils for each cylinder and you can remove it by removing the small screw(9/32) that attaches the coil to the engine. Each coil has a boot attached to it that can be removed and replaced or you can buy the coil which comes with the boot or spark plug wire. You may as well replace the plug. You will need a long extension and a spark plug socket to remove it. All you have to do is reverse the procedure. If you have any problem remove the plug once it is loose, just slide the boot from the coil on too the plug and remove the plug with it. Hope this helps leave a comment.

The coil pack on these are bad about being defective. You need to check to see if you have power coming from your coil pack. If you do not try changing it out, this produces 60k +/- volts that goes through your ignition wires, to your spark plugs and ignites the gas on combustion with the piston. If it's not giving off a spark, thenyou're not getting power to fire off the engine.

Use a squirt bottle of water and squirt the wires and plugs to see if you can cause a failure. you will know as soon as it gets wet if it is wire and spark plugs.

Sounds like two problems. P0300 and P0303 are possibly spark plugs. They could be a coil pack but I'm leaning toward a spark plug problem because of the other two codes - they're indicating O2 sensor problems. If the O2 sensors are screwed up, the car reverts to preprogrammed, rich fuel maps that send excessive fuel through the engine. The reasoning is, if the ECU can't trust the O2 sensors to determine how much fuel to burn optimally, it'll pump a bunch of extra fuel through the engine to keep it safe. Having too little fuel (aka running lean) can destroy an engine, so the ECU plays it safe and runs rich (too much fuel) instead. The consequences of rich running are relatively minor compared to lean running, but can and do tend to create excessive carbon buildup on the catalytic converter and O2 sensors, as well as fouling spark plugs.

First thing to do though is to swap the wires on your coil packs and see if you end up with a misfire code for the same cylinder #3. If you do, then it's the plug or wire. If it moves, it's the coilpack. Replace whichever part is faulty. You'll probably need oxygen sensors too, before you can clear all the codes.
