2007 Toyota Camry Misfire | How to Fix Cylinder Misfire DIY Diag and Repair

[@ivanmart135]

Thanks so much for the video! I was on my way to work (4:30 am) check engine light came on blinking ! I drive a 2007 camry ! I drove back home i was 4 minutes away found this video and I checked everything exactly like the video and the ignition coil #2 is bad im waiting for the auto parts store to open apparently u save my life I’m not spending money on a mechanic thank you so much

[@ValleyMobileAutomotive]

Hey Ivan, your welcome! Glad this video was helpful 👍

[@Phillyboi215]

Instead of doing the swapping and all that test, I’ll just get all new coils and spark plugs, problem solved and even better I’m prepared for later. Glad to see it’s a easy job no mechanic required

[@TheNamesAllison]

Thank you for making this easy to understand without unnecessary talking.

[@Gator3000]

Video easy to understand...talking clear...camera steady...great job

[@Protolamna]

I had this problem. Ended up being a surprising cause, counterfeit iridium spark plugs off of Amazon. They only lasted 20,000 miles and were burned to a nub.

[@EutychusII]

Great presentation

2:25 SO DAMN SMART. This is the sort of wisdom I love from YT mechanics. Irl mechanics look at me wild when my carpenter ass knows little tricks like this and can show them something. ❤

You're welcome 🙂

[@mscopeland]

Thank you! I'll be troubleshooting from this video!

[@OluwafemiBoluwaji]

Nice tutorial. It really help me fix my car

[@Bminson]

It was exactly my problem I first thought it was the MAF sensor then I check my cylinders and found two were bad!

[@Bminson]

The knocking and power loss showed enough but I didn’t have a tech stream so this helped thanks!

[@Romans828KJV]

My car had the same codes need to fix it 😢

[@iross2inc]

Did you fixed the knocking too?

2007 Toyota camry misfiring. Changed plugs to recommend plugs by Toyota. Still misfiring. Did your check here to see if it was the coil. It was the coil so I replaced it. 2 weeks later the new coil is bad. Parts place gave me another coil. Now that coil is bad. What is the problem? The ignition module?

[@madhatter2716]

Sucks that no one answered yoir problem or question. Would be nice if video maker actially comes back and answers comments/questions.

[@Straight-Outta-Roanoke-AL]

@@madhatter2716 I have done so much work to that piece of junk I can't even remember now what fixed that problem 🤣 it's leaking oil and dragging one leg but they still drive it every day 45 one way and back.

[@benedettocracolici197]

Oil leak could be anything, oil pan, gaskets, or even your oil mounting housing​@@Straight-Outta-Roanoke-AL

Yeah bro I tried this on my vehicle it’s Toyota Camry 2014 and it says cylinder 3 misfire yeah I tried that but it’s still saying cylinder 3 misfire can you help me with any othe idea that can help me fix this

[@ValleyMobileAutomotive]

Just curious how many miles you have and if you've replaced the spark plugs?

[@knifeaddict1014]

I replaced all my plugs on my wife’s 2012 but not the coils now I’m getting codes for 1-4 misfires

[@storkdeliverysstorkdeliver2846]

​@@knifeaddict1014 Me too. Same problem.All 4 cylinders misfire now

[@miguelartica8102]

Somebody find the problem? I have the same issue

[@rolandojrcantores7553]

what is that knocking sound

[@ValleyMobileAutomotive]

This engine has a slight knock. It's not as loud as it sounds. The camera has a tendency to amplify certain noises. Good catch

[@knifeaddict1014]

Also when I unplugged 1-4 1 at a time it idles down on every one.

[@ValleyMobileAutomotive]

When does it run rough? All the time or under certain conditions like acceleration? Do you have a scan tool that can show you active misfires?

[@knifeaddict1014]

@@ValleyMobileAutomotive well now it tops out at 40mph and almost sounds like an exhaust leak, when you give it gas feels like it slips out of gear 🤷‍♂️ 220,000 miles might be time for a new car.

[@knifeaddict1014]

@@ValleyMobileAutomotive I was thinking about replacing all the coils, I already replaced the spark plugs

[@victorgenchis]

@@knifeaddict1014Did you ever find out what was wrong? I’m going through the same issue right now.

[@uincredible]

What if there is no code?

[@ValleyMobileAutomotive]

Sometimes an intermittent misfire won't throw a code until it reaches a curtain number of misfires within a given time. I would still unplug one coil at a time to see which cylinder is missing. Then swap coils to determine if that's the cause. Possible misfire causes: Coil Plug Injector Compression Wiring to the coil or injector

[@uincredible]

I have a 2013 camry 2.5L 4 cylinder. It stumbles intermittently only at medium acceleration specially taking off from a stop sign or red light in between 2-3 gear shift. With light foot or 3 quarter gas paddle pushed, it never hesitates and runs flawlessly. Ran OBD ll scanner and found no pending codes. Things I have done so far includes: 1. Changed spark plugs 2. Cleaned MAF 3. Inspected the whole intake for leaks 4. Performed tests on coils (like the one showed in this video) The car has only 115000kms on it and it gets pretty frustrating and scary sometimes when it stumbles on a busy street where people are tailgating you. Any leads will be highly appreciated.

[@ValleyMobileAutomotive]

@@uincredible see if it acts up when you put the transmission in drive but hold the brake down and give it has for a few seconds. This puts a load on the engine without the car moving. A lot of times an ignition issue will present itself more under load. Only do this for about 5 to 10 seconds then let it idle for about a minute before doing it again. Let me know the outcome 👍 we want to know if you feel it missing when you do that and is it consistent.

[@uincredible]

Did exactly what you advised and surprisingly nothing happened. Turns out it was something else. Transmission compensation code was messed up. I don’t know how but that was the reason why my camry was having a hiccup between 2-3 shift.

[@ValleyMobileAutomotive]

@@uincredible Nice find! Thanks for the update 👍

[@stacynation1268]

I have changed the spark plugs and the ignition coils and it still misfires. I have over 2 hundred thousand miles on my 08 camry. It's only one spark plug that keeps doing this.

[@ValleyMobileAutomotive]

What codes are present? I would say then that it's not ignition related. Just to confirm you can put an inline spark tester on the bad cylinder and see if it's getting spark. If not you may have an electrical issue with that coil's circuit. I would do a compression test next as that's the next easiest thing to do. Low compression can cause a misfire. If all looks good then swap the fuel injector with a different cylinder and see if the problem follows the injector.

[@stacynation1268]

@@ValleyMobileAutomotive HI. I have no clue the codes other than its spark plug number 1.

[@nedmilburn]

Can this kill your fuel efficiency...?

[@ValleyMobileAutomotive]

Absolutely! And if gone unrepaired it can damage your catalytic converter as well.

[@nedmilburn]

@@ValleyMobileAutomotive Thank you! I have a 2011 Venza 3.5 litre v6 and I'm getting 14mpg. Mileage went really bad a few months ago, BEFORE it got cold... I changed the air filter which was terribly clogged, and my local shop repaired 2x exhaust leaks. But then my fuel economy went to pot. I wonder too about my o2 sensors but have no idea how to check them?

[@ValleyMobileAutomotive]

@@nedmilburn An issue like a bad ignition coil would be accompanied with a check engine light. You would need a diagnostic scan tool to check the oxygen sensors. If you don't have that equipment I would recommend taking it to a reputable shop. There are a number of things that can cause poor gas mileage so it's hard to say without diagnosis.

[@nedmilburn]

@@ValleyMobileAutomotive Thanks again. Our local guys aren't very good at diagnosing issues on fuel injected vehicles other than saying, "It's getting old." I have a basic scan tool. No engine error. Some sensors I hear have a large margin of error before tripping a code. Anyhow I'm gonna try cleaning my flapper valve since I feel up to the task myself and it could help. My air filter was disgusting. 4 years same filter. Local shop didn't instruct about filter. Learned about that from my motorcycle maintenance. Thanks eh!

My engine light started blinking when my car started misfiring it wouldn’t let me go over 40

[@ValleyMobileAutomotive]

Yeah when a misfire is bad enough to cause damage to the catalytic converter it will blink the check engine light. On some vehicles it will turn off the fuel injector for that cylinder so raw fuel isn't contaminating the converter. Thanks for watching!

[@trenyispretty9154]

@@ValleyMobileAutomotive could my catalytic converter be going out?

[@ValleyMobileAutomotive]

@@trenyispretty9154 a misfire and lack of power can come from a plugged converter but I wouldn't jump to that conclusion, you need to first check codes and pinpoint the cause of the misfire. It could just be something simple like spark plugs or an ignition coil and your converter is fine. But a misfire that goes unchecked for a long time can cause your converter to fail.
