@@alimohsinusmani thanks for the comment
Good explanation on knowing the causes of misfiring
Hello thank you for the video. I changed all of those u mentioned up to video and my car still shaking. Toyota yaris 2003
Are all your engine mount ok? Is it only at a certain rpm? Have you pin pointed which cylinder is causing the issue? May have to do a compression test if you've completed at the basic tests
Hello, thanks for the video, I have a question:If it was the fuel pump, why would it have manifested in cylinder one?
This wasn't a fuel pump issue. However if your asking me if it can be a fuel pump issue then the following could be the issue: clogged / faulty injector on Cylinder 1.
Thank you fit sharing. It's really good content ✅️👍🏽
@@cashisclay1654 thanks for the support
Laser thermometer on the header will tell you which cylinder is misfiring. It will be cooler.
Good afternoon all, I have a yaris 2002, 1st cylinder issue, swapped tested still 1st cylinder. Replaced all spark plugs and rods still happens every second or third journey any ideas for what to do next. Garage don't know what else it could be and car not worth much but if easy cheap fix might do it
Check your injector’s mine failed aswell
This is a good detailed video. What diagnostic OBD tool would you recommend for such a Car and other JDM cars? I have tried using a Konnwei ELM327 to no avail.
NB.. Just a word of caution, never touch the rubber tip of a coil when the car is running - I got a shock of my life.
Thanks, I generally stay away from app based scanners. Try and get a basic Autel diagnostic scanner, they seem to work well with most brands.
When working with ignition coils if live in a running engine best to wear rubber gloves to avoid getting shocked haha. Or simply pull the could as I did via the top only.
@@AutoBuddynz Thanks. I managed to connect using some strings
Everytime i put it on reverse it dies out ?
@@Nakoal-g3z is it only in reverse? Does it drive normally apart from that?
Ive got a 04 Yaris which shakes while idling but otherwise drives well. Engine management light has started flashing and the code is P0300. Do you think this could be a spark plug or coil issue?
You've got a misfire code. You can start by changing your spark plugs and seeing how that goes. Shake from the engine, is this something new which has occurred?
@@AutoBuddynz A friend told me the first code so I decided to do it myself. I deleted the code and went for a drive. Engine management light came on and I get P0300, P0301, P0302, P0303, P0304, P0171 pending. The shaking is a new thing and I dont think the plugs have ever been changed so i was going to change them anyway.
@@Dil_Playz start with the plugs and go from there.
Changed the spark plugs and only number 1 was faulty with black soot on it. Checked the new plug and this also had black soot on it. Coils have all been checked and working, there's some water coming out the exhaust. Thanks for getting back to me.
@@Dil_PlayzThanks for the feedback! If it does occur again, swap the coils around as I did in this video.
If my engine is hot then my fire will go off, what is the proplem
Impressive
Thanks!
i am interested in buying a car with this kind off engine do you think its a good engine for commuting ( 60 km work home and back)??
They are great cars, as long as they have been maintained
@@AutoBuddynz i looked at a lot of reviews
is it normal that these engine rattle?
@@69marokaan The rattle is this video is normal for a vehicle of this age. Done nearing 180,000km on the factory chain, guides etc
Very good Car.
@@tao6775 doesnt it burn oil
How can we drive so far with misfire
Preferably try and get it fixed as soon as possible. I would suggest to not drive the car unless its a minor misfire.

I need u bro , were are you
Yaris 2008
While jamming in traffic moving 10 kmph, car engine almost goes off and immediately keeping side off giving escalator it's sounds fine, what's wrong any advise
25 days in difference it happened twice
Follow the steps in this video to see if its a coil pack issue. Otherwise could be a throttle body problem or sensor issue. Get the car scanned
falling to pull when driving
Ok, could be a lot of different issues. Check the condition your spark plugs this is the best way to try and diagnose the issue.
Well presented with good explanation and practical troubleshooting.
Appreciate the comment!
AMAZING ❤
Thanks
