On 5.4 triton a cam follower could pop out and cause misfire, you can go through all the things mentioned in this video and still have an engine that is stumbling. Take the valve covers off as a last possible diagnostic, poke around looking for parts out of position.
had same issues, this code of cyl. 6 misfire and bank 2 too lean. Engine running running rough and shaking at various speeds on the road, and idle. Mechanic ran the codes and replaced the #6 spark plug and coil. Runs perfectly now and power restored. I wouldn't think one cylinder misfiring on a V-8 would shake the engine like that. Oh well, problem solved.
literally have the same problem right now, changed both spark plugs and coil but still have the issue pls help someone help idk wtf im gonna do on my 5.7 hemi
I got 2000 gmc sierra v6 with po306 code and check engine light is on and flashes regularly. Changed plugs, wires, distributor with cap and rotor, cleaned the MAF, replaced pcv valve, and poured Seafoam in my gas tank. Cleared the truck's computer for an hour and still getting the code. I guess next step is taking it to go get a compression test. If compression is good, then maybe replace the fuel injectors.
after 2 months of nightmare trying 2 fix this code and 100$ in unnecessary parts, finally found that dirt under the coil packs on the metal plate was triggering my misfires. when in doubt switch coil packs and see if the code jumps cylinders.
I just recently changed my ignition coils 2 weeks ago and out of the blue today i got a P0306... i will change that spark plug. those were changed in January as well.
Ok Champ, I'm confused.. I have a 2003 ford Expedition.. 8 cylinder .. I changed all coils and plugs myself... coils were $35 ea.. plugs were $2....I made this purchase 5-6 yrs ago they are a little more now... If I had the dealer do the work I would be out $1000 plus.. I'm saying you are quoting parts list cost for which vehicles??
I have a P0306 on my 2000 Tacoma, and even though 'they' told me it was likely, spark plugs, wires or coils, or an injector - I think it is the mass airflow sensor. Why? Because it is an existing, known issue. Many years ago I had the MAF cleaned instead of replacing it and that fixed the issue for years but now I have this CEL and I wonder if it is the MAF and not actually plugs or wires or coils, or an injector? What do you all think?
I replaced my distributor cap, rotor, spark plugs and wires last year and about 1 month ago i started getting cylinder 6 misfire should i check for the other things or check if those parts are faulty
Good question PK! Yes, we think it's better to go ahead and replace all of them if you're getting to a place where one is worn down enough to trigger a code. (i.e. a 50,000-mile mark) There is a method to our explanation though. For the sake of clarity, we want people to understand the individual spark plug is related to a specific cylinder. Also on the off chance this is happening in a new car - we want them to understand it could be a single faulty spark plug. Not engine failure. Cheers!
UGH!!! Been dealing with cylinder 6 issues for more than 6 months! I HATE JEEP! And I HATE Jeep dealerships! I have a new coil pack, new plugs, wires, and catalytic converter. Turned out, my #6 and #4 misfire codes was not fixed by replacing my Coil Pack, Spark Plugs, and Wires. Took it back to my mechanics several times. Weren't able to fix the problem. Jeep told me a couple of months ago it was my catalytic converter. My mechanics also told me that. I replaced the cat. Took it to Jeep in State College, Pennsylvania (I live in Chicago) recently, after it didn't want to start, after driving 11 hrs. Hmm. One of the worst Jeep dealerships in the US. 🤬They said one of my sparkplug wires was "loose". Took it in for in-depth diagnostic. Said my coil, plugs, wires, air intake, and everything on that long list of possible issues in the 6 & 4, passed - except they "thought" it "may" be the Fuel Injectors. I'm out of ideas, options, and $$$$. This is one of the 2 worst vehicles I've ever owned. Since day-one when I bought it brand new! It's been in the shop constantly! Can't buy another car at this time. At one time, I even complained to a notorious mob boss about Jeep, whose CEO lived about 12 minutes away from the Don. Shortly afterward, Sergio Marchionne died of "unknown causes" supposedly. But my worthless $54k Rubicon is still worthless.
I can't imagine replacing the plugs, wires & coils but not replacing the fuel injectors for #4 & #6, or at least testing them. Replacing the cat? They were just being nasty there.
i changed the o2 sensor, spark plug and ignition coil after i changed everything i manually cleared the code and it goes away for about 90 miles and then the light comes back on

Pull the plugs first, if they don't look good replace them all(unless your going the cheap route then just replace the #6 plug) and go from there. If it is still misfires then try swapping the coils like in this video (If the misfire moves to the cylinder you swapped the coil from you know that you have a bad coil and need to replace that coil. you dont have to replace them all but its not a bad idea.)and if it still misfires in the same cylinder after that swap a plug wire and replace the injector. If none of that fixes it (or moves the misfire) then you have an internal problem (Valves, Lifters, ETC.)
Depends on if your keeping or selling. I got a set of 6 coils for a 3.6 for $85 with plugs. I wouldn't buy that cheap crap if I was keeping it, but as long as it runs good during the test drive.....
Doesn't work on all vehicles. I can't switch my coil pack around because it's a bar. I've got an inline straight 6, all 6 spark plugs are in one side and my coil pack is a bar that runs across them. That being said though I replaced my coil pack and plugs and im still having problems so I think I know what it is.
@@anthonyaguirre837 nope. Never figured it out. Replaced the coil pack, replaced the fuel injectors, replaced the spark plugs, even added a heat shield. Nothing worked. Ended up having to get rid of the vehicle and bought a newer truck.

Imagine explaining that a Cylinder 6 misfire cannot happen in a 4 Cylinder Engine.

Thank you bro for that diagram map of the location of the cylinders. It helps so much.
The valves in your 4-stroke piston animation are operating in the wrong direction. Open is down. The valves open down into the combustion chamber.
Yeah, do you want that piston slamming into the valve.
Awesome video! My CEL just came on, and now I know what I need to fix. Thanks FIXD!
You're very welcome Davis! Best of luck.
Coils are usually from 60 to 260 depending on the vehicle. Mine for my truck was 56.99 for single coil
I got mine 35/ pop at rock auto. 15 5.3 V8
Silverado?
Same swap can be done with the fuel injectors to test as well see if the misfire moves to the other cylinder.
Except you must disassemble the entire top of the engine to get to the injectors so not a simple test.

i changed the spark plugs, coil packs, and injectors, any clue what can be causing the misfire? only happening in cylinder 6, no other cylinders
A short? Fuel related?

I just bought a coil at Oreilley for 40 bucks. Unsure why his price was so darn high

Thanks for the simple explanation 💯👍
In your graphics you show the cylinders being 1 2 3 on the left hand side and 45 and 6 on the right. I thought they went alternate from right to left.
Depends on the engine manufacturer with how they number the cylinders. I've seen both patterns.
