When multiple cylinders are misfiring check to see if what do they have in common. Look at scanner data and identifying which cylinders are misfiring then focus on them to try to pinpoint the root of the misfire.
INTELLECTUAL MR DIAGNOSTECH My teacher Tutorial amazing thank you for sharing it Take care and have a great Evening INTELLECTUAL MR DIAGNOSTECH From Nick Ayivor from London England UK 🇬🇧
@@MRDIAGNOSTECHThank you for the answer, I really appreciate it. I am experiencing this exact issue with my wife's car and I need to get it sorted. So this scanner is highly recommended? Any other suggestions from a professional like you?
My costumer car is having on and off misfire ford fusion 2013.. but when the A/C is on it get constant misfiring.. i need help on how to find out the fault?
nice! one thing i like add to my process is to look at trims before and after the repair to verify i dont have a lean condition...a lean cylinder is a hard cylinder to ignite through the plug. i know crossfire is common on that cap design but i always ask...why did it crossfire? is this the root cause or a symptom. a lean condition can cause spark to find an easier path to ground due to higher resistance in that cylinder .
After a rat chewed on my coil wire which was shorting on a metal tube ( ground ) when I go to live data it only gives info on 4 cylinders. It is a 6 cylinder. In the past my scanner gave info on all 6 cylinders. A standard coil puts out 20k - 30k positive voltage. With that much voltage going to ground I think it has caused a problem inside the ECM. What do you think? I don't see any other damage to my wiring.
Good morning sir, i have a 2003 DODGE CARAVAN SE V6 3.3L, it's giving me code P0300, i did a cylinder drop test using a test light removing one wire at a time from the coil pack while the vehicle is parked and idling in a house garage, i can't tell which exact cylinder is misfiring, should i redo the cylinder drop test using the test light while doing a brake torque test and removing one wire at a time to see if i can tell which exact cylinder is misfiring?
Really appreciate your time to put out this videos. Grasias por poner estos videos. Pudiera communicarme con usted si tubiera pregunta en cosas de mecanica. Grasias.
I had connected think car mini in my Mazda and I have seen some misfire in random cylinders and all 4 cylinders got 7-8(on each cylinder) random misfire per 30-40 minutes trip. But there's no trouble codes pooed up. Should be worried about it? Thank you in advance 😌
Thanks for the video. Are there any affordable scanners that show live data on cylinder misfires? I have a 2010 Honda Pilot touring, and the check engine light is blinking. I was considering checking the spark plugs and coils once I read the data if it is showing misfires. Thanks
Agradezco tu atención. Estoy inscrito en tu canal, y en lo sucesivo veré los videos de tu canal, ya que tú, explicas bien y de forma detallada. De nuevo Gracias, bendiciones.
Do you know of a scanner that I can purchase that will give me access to LIVE misfires on a 2004 ford mustang? I bought a cheap $100 scanner that gives me mode 6 but problem is it doesn't track it live and when it shows a misfire in a cylinder I have no idea when that misfire was recorded. I am chasing a very intermittent idle only shake that I believe to potentially be a misfire and I want to rule that out by getting live data. If when the shake happens and I can see that there are no live misfires then I can pursue other potential causes like engine mounts/harmonic balancer etc.
There are great scanners out in the market. Not every scanner will do everything, I would suggest an Autel scanner that has an oscilloscopeintegrated, it's not too expensive and has a lot of features. There are different model numbers available with similar features and some within more.
Hi. I'm looking at getting a low budget scope. Have u tried any of those China products? I have a scan tool, but I'm seeing a serious need for a scope.
You are looking for the number of misfire counts, it should be zero. If it's misfiring, it will display the number of times that cylinder(s) are misfiring.
@@EARTHKEENING The history shows the amount of times it has misfire, when the engine is off, the counts are zero because the engine is not running, but once it's running and you see numbers besides zero it means that the engine is misfiring.
What is the name of these OBD ? Do you have to pay every year to used these OBD ? If you dont pay every year or monthly Does it still works ? Does it Scan for Fuel Pressure Does it Scan for Compression testing Like Sparks ? So if you dont update for example does that still works ?
Estimado Amigo. Tengas excelente día. Tengo 2 preguntas referentes a lecturas del scanner. hago la aclaración, yo se poco de inglés y mi scanner está en idioma inglés. bien, 1 Mi primer pregunta es: Que significa FUEL TRIM CELL, yo sé que ==FUEL TRIM== es referente a los ajustes del combustible a corto y largo plazo, pero que significa FUEL TRIM CELL, se refiere a qué, es una pieza o componente del automovil. 2 Mi segunda pregunta es referente también a los ajustes del combustible. El scanner muestra command air-fuel equivalence ratio (1 value número rojo) y 1 unidad, esto es igual a <a href="#" class="seekto" data-time="61">1:1</a> De antemano te doy las gracias por ayudarme. Fuerte abrazo y saludo desde el bello Puerto de Tampico Tamaulipas México.
Estimado amigo, Fuel trim Cell es una calculacion de injections ge gasolina basada a la efifiencia volumetrica del motor. Esto significa que basado a las revoluciones y la masa de aire que esta entrando al motor la computadora va a utilisar cierta estrategia de injeccion de gasolina.
Claro que soy Mexicano con mucho orgullo y a mucha honra. Que tiene de malo que mi canal sea en ingles? Baya baya tacubayaa si no conose mejor no bayaa.
