Sounds to me like a bad coil on number six or a bad connection either at coil power or coil high voltage terminal, I'd ohm out the coil against another one or swap it to another cylinder clear codes and se if the problem moves to another cylinder..

Have a misfire in cylinder 6 changed all coil packs all spark plugs stills says cylinder 6 misfire


A misfire could be caused by almost anything, spark--fuel--compression. Did you check for spark at number 6? All electrical components have voltage and ground, if problem on wiring circuit, replacing the component won't fix it.
Also, check for fuel injector pulse--proper fuel pressure and cylinder compression.
I don't know year--make--model, it didn't post for some reason?

Misfire in #2 cylinder over 1500 RPMs 2006 Scion


I would try swapping coil #2 with on of the other ones and see if the misfire changes to the other cylinder. If it does you have a bad coil. If it stays on cyl.2 check the spark plug wire or fuel injector.

New plug misfire in dodge ram 1500 6 cyl van


could be your coil, but can also be internal, have you replaced both the air & fuel filters ? if so, dump some good fuel injector cleaner into tank when half empty , top off with 91-92 octane fuel, see how that works for you, do some highway driving, stop & go traffic creates problems, todays fuel w/ethonal is bad for older cars, be sure to have code cleared from ecm !

Number 3 and 4 are not firing from coil on 2002 subaru outback 2.5


its faulty coil.

Get the compression test done on each coil.these will let you know if its faulty coil or not.

=========

It can be issue with spark plugs or faulty spark plugs. Also get the compression test done for cylinders. If any of cylinder shows low compression then required, then that particular cylinder will cause misfire.

Also get obd codes scanned, the error code will let you know which cylinder is misfiring or all cylinders are misfiring.

06 Dodge Ram 1500 P0307 code


You did not say whether or not you changed the plug wires when you changed the plugs. I assume so, but if not you may want to try swapping the #7 wire with another wire of similar length at both ends and see if the miss goes away or moves to the new cylinder. Visuals can be misleading with plug wires as they can be easily damaged and break down with age. If they are original to the vehicle, I would not hesitate to change them at this time. The "lack" of miss at highway speed, on an 8-cylinder vehicle, is often the fact that it may not be felt when little or no engine load is present. Other than that, the miss could be caused by a leaky valve (most likely exhaust). This would result in low compression of the cylinder, resulting in misfire. A compression check will find this easily. Leaky fuel injector can also cause misfires. If the cylinder gets too much fuel, the spark may fail occasionally, causing a misfire condition. There are other things that can cause misfires, but not in just a single cylinder such as you describe.

Look at the spark plug, if looks ok then that's not the problem.with spark plug out check cylinder compression if good then check fuel injector, reinstall spark plug, start engine and listen for clicking noise at fuel injector, if none bad injector replace.

Check engine light


A multi misfire may mean that one or more of the following has happened:
Faulty spark plug or wires, Faulty coil (pack), Faulty oxygen sensor(s), Faulty fuel injector(s), Stuck/blocked EGR valve / passages, Faulty camshaft position sensor, Defective computer.

The engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wire, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the the problems were faulty fuel injectors. 

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

Good luck and hope this information helps, keep me posted, be glad to help you get the truck running 100% again. Not sure if your running a K&N air filter, and if you are there may be a flim of oil on the MAF sensor that is making you run lean. You may want to spray down the MAF sensor with a can of MAF cleaner.
