Ford Explorer 4.6 PO308 common Misfire code. Easy Fix *F-A-S-T!*

[@FixingWithPassion]

After you clean out the moisture...if it starts to miss again...check for moisture again! If you find moisture, its time for a new intake with gaskets.

[@Definitelynottheatf]

TVWXMAN32 ur a life saver, I was about to change my ecm because this issue

[@robertberin4872]

Any videos on how to change the intake gasket to fix the problem for good?

[@BUZZKILLJRJR]

Great video, super helpful, all done! Subbed too brother!

[@rickwoodruff8211]

Five years later your post is still helping people! You helped me fix my Grand Marquis! Thank you!

[@lanceanderson9192]

I have 1997 F150 4.6 skip on #2 Your fix was on the money moisture in that hole. Blew it out and smooth as glass. Many thanks.

[@FixingWithPassion]

Great! Petty common on them.

[@2bitgypsy]

Thank you very much for sharing this info. I have an '07 Sport Trac that developed a misfire out of nowhere. In hind sight and with the knowledge I gained here, it was right after we had a significant snow melt. The scanner said #8 Cylinder Misfire (P0308), and that led me to this video. I pulled the #8 coil pack and sure enough it was wet. I got it all dried up and, luckily for me, my coil still seems to work and it's running smooth again! There is no other evidence of leaks, so I am almost certain it had to drip straight in off that plastic clip Nathan pointed out. Thank you again for the video, it is especially useful because I think this particular issue is probably Explorer specific. There are other good videos about the 4.6 in other vehicles that don't address this quirk/feature.

[@FixingWithPassion]

Nice!!!

[@kentkurt9065]

Had the #4 missfire lol those three cowl fassening holes couldnt line up more perfect on #4 , and #8 coilpacks on my 02 ex.. going to make a deverter so the water runs down the back of the motor . Awsome video !!!

[@jazamaraz8029]

Thanks, Nathan. This is almost certainly the problem I'm experiencing with my 4.6L Expedition. I have a P0308 code after a week of two of hard rains. Now to find the time to do the work.

[@tinasells3998]

holy moly ..... my 06' explorer is doing the same thing ... almost took it in to the dealer for a fix....i think ill try this first ....save some moola.

[@FixingWithPassion]

ok!

[@hankbridges5055]

Put fuel injector cleaner in regularly to avoid some codes, Clogged injectors, sticking IAC valves, clogged EGR, etc. Leaky injectors can burn up the converter. A EGR that doesn't open damages the converter. Try brake cleaner on intake gaskets to locate a leaky gasket. Code testers can do a cylinder balance test.

[@Wrenchingdaily]

Run a thick bead of dielectric grease just below the upper lip of the boot where it meets the top of the spark plug well. This will keep water out for awhile until you can replace the intake. Worked great for me

[@robertberin4872]

This smoothed out a badly shaking car. Also it cleared my catalytic smog fail. Thank you very much.

[@FixingWithPassion]

Yea!!!

[@baileytadlock1623]

Will a 2005 with the 4.6 have tranny problems? Buying one soon and could use the info!

[@FixingWithPassion]

Depends...

[@victoryfirst2878]

Sir, do you know where I could buy a ignition wire kit that is low resistance helical wound center conductor ??? I have V6 engine in my explorer. Thanks

[@eagleeagle7802]

The best one and fixed I've ever seen thanks

[@slotman7284]

You was right it fixed my problem...thank you alot..

[@treasurecoastwaters8400]

great thx for the upload. really good!

[@FixingWithPassion]

Nice!

[@regthebackyardjackofalltrades]

Thank you very much for this. I cannot afford a new car now but I have the time to replace these parts. I’ll purchase 8 coil packs and replace the plenum gasket.

[@FixingWithPassion]

Nice!~

[@jeremiahbryant9814]

Work for me thanks

[@DanielPerez-ee3wp]

Good evening. Question, the 7 cylinder coil is on the back driver side?

[@dennyadkins21]

Good information. I was looking at one with same issues.

[@FixingWithPassion]

Nice!

[@papo862]

I have same misfire took plug out had very little water thanks for the video was about to go to mechanic.

[@victordiaz2627]

Thank you that was a big help I save money

[@FixingWithPassion]

Cool!!

[@USCGPHOTO]

Worked exactly as described. Thanks

[@jackmonk1970]

Fixed mine just now thanks brotha 💪💪💪

[@FixingWithPassion]

That's so cool. Nice!~

[@jackmonk1970]

@@FixingWithPassion still dont wanna take off on eway I replaced the 2 coils 6 and 7 then took it to auto zone and they just told me all 4 coils on that side is reading bad ...what should i do now any suggestions ?

[@jackmonk1970]

I did that and only 1 remained the same and I sprayed it out it changed the jumpy take off but on eway still feels like it dont wanna accelerate

[@theshifty46]

Fix worked perfectly for me. Out of curiosity, how frequently does this recur? What state/country do you live in and do you get large amounts of precipitation or humidity in your area?

[@FixingWithPassion]

I live where we get 40" of rain a year. Water like pooling around that coil.

[@boscomonga3331]

Salut j ai un problème avec mon ford explorer v8 ca ne demarre plus et le devant tableaux de bord il ya un signale rouge qui barre la clé. Comment démarrer et enlevé le barre cle?

[@Novagunner]

my mustang is doing this, i just bought all new coils, i know all new isnt necessary.. but its my project car so i really look for any excuse to spend money on it new coils and plugs hopefully thats the ticket.. next it replacing the Plenum... to make sure that gasket you refrence isnt bad, but i need a new one anyways because those little brass fittings that the bolts for the coils thread to, are stripped... so i ned a new plenum just to replace those lol

[@gregcxox5562]

This really is an issue with these trucks. I also recommend pulling the plug and cleaning it since your right there. Depending on what fluid is in there it some times turns to a gummy jelly on top of the plug and fouls it out. Air will not remove that but a shop rag will.

[@FixingWithPassion]

Yea its like non-stop issue with fords.

[@mediaguy4037]

I have p0308 on a 4.6 Crown victoria 2011.....Changed coil pack, still misfires. Old coil was dry when I took it out and intake was already replaced by the department that had the car.......so my next attempt will be all new 8 plugs.

[@robswrenches9501]

Thanks for the info. I'm enjoying your content. Keep up the good work. 👍👍👍👍👍

[@mariohdz3212]

Nice video amigo 🙂. I will subscribe 😃😃

[@citybankrupt]

Thanks tx32...I have the same leak on a Lincoln aviator .It would be nice to redirect rainwater away from that drip,but before that I have about 800 other ford oversights to torture myself with. Any tips on how to deal with a po2195 code? pretty sure its not a intake or hose leak.

[@FixingWithPassion]

I know right! If you have that plastic intake. I'd start there for a crack or bad gasket in that thing. The thing is you have to replace both in order to fix it right. I did mine for less that $150.00 got the intake and gaskets on e-bay from a dealer. did it my self. Ran like new after the fix!

[@EarlGuyton425]

You missed something BIG here. The first coil you removed you didn't remove the boot and spring and clean and dry the spring contact area. As a rule all people need to start doing this before replacing any coil because these get white and green corrosion at the metal contact where the spring fits inside the coil. Those coild probably never actually go bad as for your windings but build up corrosion same as older cars in where the inner distributor post had to be cleaned and the rotors

[@FixingWithPassion]

Thanks. I did this later that night...I almost forgot.

[@donaldjandl3236]

thanks very though,lots of aelp

[@FixingWithPassion]

Thanks for the info.

[@jenniferspath963]

Hi there! I removed my coil and used compressed air to clean out. There didn't seem to be any moisture. I put new coil back in and there's still a misfire. Should I check the plugs next? My check engine line is still on and I'm not positive if I'm hearing a change in the idle with the new coil.

[@FixingWithPassion]

yep check plug

[@jenniferspath963]

@@FixingWithPassion the check engine light ended up going off. My mechanic said the plugs are fine, guess my cat just took some time to register it. Thank you for the video and response!

[@lakotamason7748]

Couldn't I put some dielectric grease on the boot to help with water

[@FixingWithPassion]

yea

[@mustangmatt410]

Are these SUVs normally loud. I just brought one with a 4.6 v8 and its sounds loud to me. No aftermarket exhaust.

[@FixingWithPassion]

Compaired to my TrailBlazer I think there a bit louder. The explorers have issues with a noisy torque converters, the springs get weak and "rattle".

[@m0v3mental60]

Matthew Torres or a leak in the exhaust system can cause a louder noise.

[@cp122578]

I have a Ford Explorer V8 5.0. I had someone put it on the computer, and it shows misfiring on the 7th, instead of the 8th cylinder. Will I find the same problem that you describe on the 8th? The mechanic wanted to replace all of the plug wires.

[@FixingWithPassion]

Look for a wet coil on 7&8...common places for that.

[@shrek66669]

I threw a bottle of lucus upper injector cleaner in and it cleared it out over the course of a tank

[@FixingWithPassion]

Nice!

[@mustangdanny97]

Replaced my intake on 03 explorer 4.6l. Got coolant in spark plug hole I didn't know it.i put coils back on and threw codes.so I took coils off and blew water out.now car is misfiring but no codes.do u think I fried coils?

[@FixingWithPassion]

Good find.

[@mustangdanny97]

I'm sorry I didn't understand your response

[@seaandskyandseandsky]

I had this error.....and attacked "everything"... having not seen or heard about this fix.. 2001 Expedtion xlt. 108000 miles. I bit the bullet and took on the task of replacing all plugs and coils. GEEZ what a hassle!. I am 6'6 and had to still stand on a stepstool wearing a strong LED headlamp while scraping up my hands. I removed the two bolts on either side holding the fuel rails, then pried them up and "tied" them back an inch to see the spark plug holes. The ones in the back are pretty hard to get to!. On one cylinder, I got the plug captured by the 5/8 spark plug socket, unthreaded it and then the extension tool kept popping out of the socket/spark plug. I used a STRONG magnet tipped tool to insert in the hole to finally get it out. By the looks of the plugs, I think they are the original Motorcraft ones...huge gaps.... Glad I am doing all of them. I am taking a chance on using new "inexpensive" coils from Amazon rather than the way pricier Motorcraft ones. I am wondering what a Ford dealer would quote for a "spark plug replacement" labor cost. Whew.. I sure like working on my 1990 Miata engine now!!!!!!!!!!!!!!!!!!!!!

[@sifulowang]

Whenever i remove the loose plug or insert new ones (NEVER trust the factory gap, never) i use a foot of 3/8 misc fuel or cacuum hose on the plug tip. Read it on the back of an old hot rod rag. Life giver.
