07 Tahoe Misfire Cylinder 7 | P0307 | Collapsed Lifter  

I've looked at hundreds of videos and yours is absolutely the best that I've ever seen. Thank You

Amazing video. The only reason why I attempted this repair was because of your video. Thank you very much. Your honesty and your easy to understand steps made this repair fairly easy.

Very good job my man I have been fixing cars for as long as I can remember and for someone who doesn’t you did a fantastic job very impressed… 👍👍

I have the same problem too on my 2008 GMC Yukon. Thanks for your video bro!!! Appreciate these types of videos because we aren’t professional mechanics and these type of jobs they will try to take all of your money. Great work!

Bro I'm proud of you doing this so far because I can't go far like u did tanks for all u teach

Thank you so much for this video. I couldn’t get past the fuel injector connect. This video save me a fortune. I was able to get my lifter unstuck on my 2009 Silverado.

I have the same issues with this Tahoe that I’m using. Will be doing this after this state thaws out. Thank you for the video!

Solid content and source of info for someone who’s not a mechanic. This should assist someone in the right direction of diagnosing what may be the culprit.

You did a great job on this my Brotha! I’m the same way.. I’ll give it a shot myself before I take it to a shop and get ripped off. Especially, one they get real high mileage I prefer to try working on it myself.

My hat off to you, for someone that said they never did anything like this before you did a great job. Best thing to do is take your time, take pictures and videos and never be afraid to ask questions. I did notice your oil pressure was low before and after. On some of these 5.3 the O ring that holds the pick up tube goes bad and you suck up air. It is an easy fix also. Not sure if that is your problem. As a master tech of over 30 years, I must say good job

Guy here is better at teaching than anybody I’ve seen so far on RU-vid I really like this guy and I’m gonna like and subscribe to everything that

You talk about your Tahoe the same way I do 🤣🤣 Glad you were able to save her. I got lucky...I was able to disable my AFM before I ever had a lifter problem. 233,000 miles and going strong.

WOW! My Suburban stand still for 3-4 years. Now i see your video. I will check my Engine and i think this is the problem of my car. Very very thanks from germany! :-)

Your video was very genuine and enjoyable. Great job!

It’s a really great job..!!! Thank you, really appreciate your time on this video, easy to understand and very very helpful. Thank you for share it with all of us. 👏👏👍.

Thanks for the video. I have a 2004 which is not a supposed to have AFM but I have misfires and don't know why. I glad you let us see how you fixed the lifter.

Thanks for the video. I’m having the same issue and the lifter is the last thing left. But appreciate you for putting this video out as I’m about to dive into mine now. Mad respect for you bro. You did the job honestly and gave credit where credit was due. I got mad respect for you. And really appreciate you taking the extra time to make the video. Thanks again bro.

Great job videoing this post. When you startled removing oil sending unit and the plate it was attached to lifted and you had all the bolts riding in the holes I almost choked! I could just see one falling into engine! I couldn't tell if you shop vac that intake area before going any farther but I hope you did. I totally enjoyed all of it.

MA Brudda, am driving to work today and THE SAME THING happened to me, I stopped @advance auto, changed the coil, wires....bit it did not fix it... I think it's a stuck lifter just like you said... I will Rlrea H out for the AFM delete... Thanks man🎉🎉🎉 cheers... I was @ a loss with this....

Great job for a first time. Its my first time going to be doing the same and i was intimidated until i watched your video. Thanks for the motivation bro. Amazing job again bro 👏 👍

This video is the best I have found thanks very informative

Love your video brotha. This helped me out a lot cause im struggling with money right now.

THANKS FOR THE INFO LEARNED SOMETHING NEW TODAY LOL

same issue, great video to help non-mechanics diagnose. luckily mine was just the plug

Hey I'm in the same boat working on my neighbor 2013 suburban with the same problem. Just hope it's not a collapse lifter. Not bad for a first timer 👍. Your commentary is funny 🤣!! You saved a lot of money doing it yourself. That is the reason why I started doing my own repairs. 🇺🇸 1st 4ever

hopefully you got this fixed. collasped lifters means its time to afm delete. the afm system goes bad after like 50k miles and usually causes hella heartbreak. more if you have an upgraded camshaft. same thing happened to my car rn. ordered an afm delete kit, new pushrods, springs, etc that the person who had my car before me should have but didnt when they upgraded the cam. but the afm delete kit from a site like texas speed will fix this issue and give you the options you need to make sure it doesnt happen again. Also i would suggest link bar style lifters. why? one less fail point by removing the plastic trays all together. if u dont believe look up what happens when ur plastic lifter tray starts to get old. gl gb if you do the new lifters you can also add more hp to your car. glad to see you got it all sorted and this will def help my problem so you did help a bro out lol.

Great video! Huge help!!!

Same issue here, and we’re learning as we go. 🛠️

Our 2009 tahoe has this exact problem. Have to 2 foot it at lights to keep it from dying, stabilitrac, abs, flashing check engine. Same code as yours gonna see about a range disabler for it too. Appreciate the vid man

Yeah most common thing when this happens I just found out lifter will go bad so need to replace that but also make sure you replace the oil pan pick up tube o-ring and while at it replace the oil pan gasket as well won’t hurt to replace it since the oil pan is gonna come down. I will be doing this to mine as well

Thanks a lot my truck was running my crazy 👍🏾

Thanks for the video I’m going to try and fix mine now

good job I have 04 chevy silverado pickup work truck went thru went through same thing bought 2 modest priced OBD- diagnostic (7 to 10) via amazon 2 diff brands both saying same thing been thinking for few weeks maybe it's just that darn computer I going to get it checked out gotta save money where you can save it , saved money is made money

Now you have me rethinking the problem with my LS3 6.2. when I was doing my remote start in the morning I would hear a faint tick on the driver side then all of a sudden blinking engine light and stability control service light. Live data shows ,#3 misfire . I change plugs wires and #3 coil, still have misfire engine shaking. #3 plug it's not one of the AFM cylinders which are 1,7,4 and 6. So maybe I have a stuck lifter like you had.

Ugh same issue misfire cylinder 7. Tapping. Sitting at mechanic rn. Im out of town for the week. May just take it back and do this. Great video

Gracias por tu vídeo yo tengo el mismo problema cilindro 4

Man you just helped me out alot, headhunter is doing the same thing only diff cylinder 4 misfire, I've liked, here's my comment and I'll subscribe Dogon, thanks bro

Thank you you friend! Very helpful

Man.... At first I thought nah, because I have the same ride as you and same pride as you and same problem you had I stuck with it. Holy s*** bro they ought to call you Captain save some doe$

Nice my only recommendation would be before removing the vlom is to clean up the debris a bit avoid dropping extra spices into the void haha. But very good job.

Great video, thanks for the info,

I have the exact same truck only mine is black. It's running rough and giving me a code for deactivation cylinder solenoid #7 . I'm going to buy my first set of tools and do the same thing. Thanks for uploading the blueprint bro. I'm still paying a note on my truck. You're heaven sent.

You did a good job there, I'm having the same problem with my 2009 gmc as well, it has the same engine

Thx man !! Hella helped

I change the spark and switch but still problem what happened

This video just saved my ass. I'm 90 percent sure this is what's going on with mine.

Bro the 10mm line got me 😂

Good video man..

Great video I’m having Similar problems I have a missed fire on number six change the core pack and it’s steelRunning rough should I take it to the Chevy dealer

So what was the problem ?

That flashing check engine light can also happen if you have a leak on your fuel rail, i had an idiot that swore up and down he was a mechanic work on my vehicle and he took the fuel rail off to replace knock sensor, i took it to a real pro and told me it was spraying fuel at my fuel rail

Appreciate the video bro, quick question Did you loosen up cylinder seven or did you just hit it with a hammer till it goes up and it catches the spring? Thanks in advance 🙏🏽

What city are you in I am having the same problem?

Got that code today…..gonna be fun

Thanks man damn great job cause you showed me what’s going on with mines but where did you order the vlom mod from I need one

ey bery good job my friend and , you are right those vehicles are our babies ,, I love mine also ,I can understand you 100/100 god job on your Tahoe I'm thinking if I'll try to fixes by myself or wait for the mechanic hi sai wait a week 🙄🙄🤷🤷 so.....

Maaaan my pick up just starting doing that 🤦🏻‍♂️ then got the video ,,so now is my turn to fix mine

Good job 💯💯💯💯💯

Well done ✔️

He pulled up to the scene wit da cylinder missing! 😂

I had the same problem except my truck had a tap on cylinder 6. Thought it was a spun bearing, or the flexplate. Turns out the dod/afm system caused this to happen. I would seriously consider doing a dod delete bro, bc it probably will happen again. The dod system works good until you get up into higher miles then it starts failing. I'm in the process now of a cam swap, a non dod valley cover, LS7 lifters and tray, high performance pushrods, and LS7 valve springs. They also have a device made by range that you can plug into your ob reader port that turns the dod system off as well.

Yo im glad you fixed your truck, im also having the same issues with my truck. i have a 07 sierra and i first got a misfire on cylinder 4 code p0304 then i changed all the spark plugs and i got a random misfire with the code p0300. i ended up changing my coil and spark plugs wire and its still doing the same thing. someone told me that ac delco spark plugs are recommended for my truck but i used bosch spark plugs, im wondering if you think that can be an issue? also what did you do to finally fix the issue?? im not trying to drive my truck like this since it shifts rough on 1st gear and im not trying to mess up my transmission. thanks in advance, i also did remove my throttle body and mass air flow sensor and cleaned both but no luck.

Do you take off the black part that's inside of where you put the vlom modification from craze performance

Good job man

Thats a tough job. Love these 5.3L V8s. Good job. Range AFM Delete is all you need to disable the V4 mode. Plugs into OBS port.

My 2018 chevy just messed up on me and is doing the hard knocking as soon as i start it and shakes too the same. I think is the lifter on cylinder 7 checked on autozone missfired on that one. How much is that vlom? And that little piece to put in there?

About to do this same thing.. appreciate the video 🗽🗽🗽🗽

Good job!!!i have a Chevy Silverado and it has a misfire on 6 and 7 wondering if it’s the same issue

What is the piece of rod you tapped to loosen the lifter?

I have a Toyota Camry 2001 2.2 Liter engine 4 Cyl . I have this kinda problem. Flashing engine lights on and Misfire Codes. After changing my Spark Plugs and New wires and New Coil wires .It still Misfires. Then I change my Fuel Injectors Change Oil and put some Lucas Fuel Injector cleaner Still Misfires . This is the Codes that is Showing up P0300 Random /Multiple Cylinder Misfire P0301 Cylinder 1 Misfire P0302 Cylinder 2 Misfire P0303 Cylinder 3 Misfire Now iam thinking changing my Fuel Pressure Regulator .So is this going to solve my problem on my vehicle .I heard some people will say that the timing chain is the problem .and some will tell me that it is Intake Valve Not Setting Properly .

hey man, what is the deal with your oil pressure. It looked like it was low after the mod you did. cheers

I’m having the same problem with my 2009 Silverado. I changed the spark plug New wires new ignition coil. And still misfiring on cylinder 8 I was thinking the same bad lifter. And after seeing this video. I believe that’s my problem. I’m going to check it out thanx man. Good video man

Is truck still running good after u fix it I was just wondering cause I’m planing to do mine like ur

I think I am about to have to do this to cylinder 1 on my 2011 yukon denali..showing P0301 code AFTER I changed cylinder 1 coil pack and ALL of the plugs and wires. I need the afm delete for sure.

I'm going to try that delete and that's all I had to do was open them passages , and get the afm tuned out of the pcm ?

Good job brother I’m having the same problem with my RAM and I’m thinking about doing the work and saving myself $3,400

Planning on doing this . Mines is number 4 should I just go ahead and take off intake and get into the lifters or should I start with sparks and wires etc 1st ?

hey my man let me tell what is its the PLENUM INTAKE GASKETS.BELIEVE ME MY 2001 SUBURBAN HAS 4000.000 MILES ON IT AND LAST WEEKEND I CHANGED THEM AND IT RUNS LIKE NEW.IT WAS IDKEING UP AND DOWN ESPECIALLY IN THE MORNING COLD WEATHER.NOWI IT RUNS AT 500 RPM STEADY..

Hi did the engine have a tick noise from the collapsed lifter??

Hey great job, when you released the lifter with the screwdriver shaft did you remove the rocker arm? You said you wished you got it on video but everything was still together. Crazed Performance has always had the rocker removed and the rod flies out. Thanks!

How long did it take to send the computer out and get it back?

When you add the spacer? Do you still have to add in the oil pressure filter also or does the spacer replace that?

Hi First, thanks for the help I did exactly the same as you, but in the minute 26.33 I did not understand the exact method of repair, how is it possible to explain more, thank you

So I replaced the lifters on mine and it still misfiring idk if it maybe bc I didn’t change the spark plug wires n spark plugs or even the coils

You was very helpful I do my own thank tip computer have reset thank man

How long did it take you to do the job.?? I knew I just changed out my plugs and wires not to long ago. As well first time changing the pack… thank god I didn’t buy all eight packs… I put would have cost me $500 I’m like dang… I had an idea to check the valve due a afm cly 4 thank god it’s only one rocket arm… but as they say might as well change them all and delete… I got a ava 07 and this video helped a lot… thank you… I sub and liked…

I am having exact same issue . Wondering if that is the issue . When I hit the gas it makes a clanking noise

I got the same problem did you just torque the lifter or did you replace them all?

Trying to solve 2010 Sierra with similar issue on #1 which is part of AFM. I swapped #1 and #3 coil. Installed new plug on #1. Made another code pop up. It is too cold here to pull engine apart. I want to test wiring tonight before I tell nephew to take it to a shop.

I have the same issue on mine just wondering was your truck turning off?and the smell of fuel is strong on mines

Hey man! Great job. Have a question. Did you reset the lifter like the other guy said? After release did you have to hammer on the push rod to lock the lifter back down? Thanks

Any updates on how your tahoe has been running

The spark plug on the right is not original. I bought the same one and it made me suffer from many faults

So did you actually fix the lifter problem or did you just use that punch on it and collapsed in it fixed itself and if that’s the case, wonder why it was stuck to begin with

when you worked on the lifter you said that you had to torque it? what was the torque spec and what did you actually tightened? thanks

didnt you have to change the cam shaft also? that's what I heard you have to go to get rid of the fuel managment

I am having a misfire and I don’t have the money to pay someone to fix it so I am hoping this helps

So what was the real issue ?

My 2007 suburban misfiring changed all the coils and spark plug wires not plugs its still running like shit pulled the driver side valve cover no lose rocker arms

what type of rod did you use to unfreeze the lifter ? Where did you get it from ?
