Sounds like the ignition wires,from the coilpack to the plug,or the coilpack itself

Running rich


Hi Justin
you seems that you have a good idea about engines and injection systems, lets say that the computer see's rich exhaust and pulls back fuel mixture. creating misfire. why the engine is misfiring on one cylinder only??
my advice to you
1 search for a vacuum leak corresponding to the misfiring cylinder, like a manifold gasket or injector seal.
2, do a compression test for all cylinders, probably you have a burnet valve.
Good luck and let me know how it goes.

MY 04 KIA SEDONA KEEPS SAYING MISFIRE IN CYLINDER 1 AFTER I'VE CHANGED THE WIRES, PLUGS, COIL PACKS 2X, ALL 4 LIFTERS AND THE FUEL INJECTOR. WHY? AND WHAT AM I DOING WRONG? THANK YOU IN ADVANCE.


Fire it up at night and look for arcing in the dark. It may also be nothing more than number 1 plug wire misrouted in a way that inductively picks up energy from one of the other coil packs or cylinders. It should cross other plug wires only once.

CYLINDER 1 MISFIRE?


Check the spark plug gap on all of your spark plugs.

What sensor would cause misfire on a 2002 Kia Sedona?


if it is really a sensor problem, this should be crank position sensor and/or knock sensor. those are all related to ignition system.

2002 kia sedona is misfiring after plug change


The problems could be that a plug was not gapped correctly or needed to be gapped and was not. Easily the best thing to do would be to remove it and check it to see. Visit your local Autozone as well and have the codes read, if there is indead a misfire, there should be a code that will tell you in which cylinder exactly the misfire may be coming from. If the spark plugs are not causing the problem, then you can retrace you'r steps and check the plug wires or coil.

Hope This Helps!

Skippng and misfire on cylinder # 4. How do you know if it is a fuel injector or a coilpac? Is there a way to test either or both? Since the each coilpac is for a dual cylinder should you get a dual...


Fuel injector should 'click' when working, and a fuel injector tester can light when a signal comes from the computer.

Coilpack for dual cylinder can be switched around to see if the misfire follows the coilpack in question when codes are cleared and it is rescanned.
