  Thank You for sharing your knowledge, Great Video. I hit the bell !!! I’m not a tech , mechanic, Etc . Was getting frustrated a year ago with a P0304 code . Spent way too much money , having my vehicle diagnosed . Decided to try to educate myself and find out what causing misfire . I believe in paying for a diagnostic tests , but when you find out wasn’t test driven , cleared codes , freeze frame data ETC $1200 bucks later engine light flashing after 2 drive cycles (Ford) ! Misfire gone for 8 months , fuel trims , MAF , EGR , Etc all working as they should again . I continue to learn as much as possible, my new hobby . Love when my husband, kids , ask me any question about their vehicles . Thanks for sharing a fantastic, informative, show ! Watched twice !!!! 😊 thanks from 🇨🇦🇨🇦🇨🇦🇨🇦🇨🇦

  So the difference between the ignition and spark misfires here is that for ignition misfire the O2 signal goes lean because of the unburned air from the bad cylinder while for an injector misfire the O2 signal goes rich because the catalytic converter absorbs the Oxygen from the bad cylinder?

  The voltage went down first when high rpm returned to idle. When the coil was unplugged the voltage went higher?

  No, the voltage went lower because lack of spark. If it was fuel-related the voltage would have gone higher.

  It seems to me he didn't rev the engine AFTER disconnecting the coil contrary to what he said earlier. The engine started sputtering after the coil was disconnected after which the signal went rich quickly.

State emission and the ppl that enforce them on the proletariat but not the bourgeoisie can go fu*k themselves.

  How does the AP2500 compare to AP200 which is a similar tool for similar price? the Autel site will not compare the two tools. Do they both scan the HVAC system? No details are available, just some random screen shots.

  the 250- allows you to choose one car line for complete access to all the modules for free. so in your case about the hvac module, you would want the 2500

  The one issue I see is that when connected to a vacuum line with a pulse sensor you’re seeing each cylinder pulling on the intake manifold but you’re not seeing anything to do with the exhaust valve. A pulse sensor doesn’t show true pressure it just reacts to the change in pressure and the voltage rebounds the opposite direction afterwards. Thats why you see the downward slope. The exhaust valve isn’t visible from the intake manifold as the intake valve is closed when the exhaust valve opens.

• 
  @electron-john2 ай бұрын

  I have been able to find exhaust valve issues with the pulse transducer . due to valve overlap on engines, an issue with the exhaust valve will be prevelant on intake pulses. if you’d like I can try to share a scope pattern showing an issue when I return from traveling.

It does bidirectional testing and all systems scan. Live data has everything you can think of. The Xtool A30M is the only tool to get other than a professional scanner. it's almost like having a pro scanner anyways. Do a review on it next maybe. 👍

  hi sandy, level 1 can be found on the paid subscriber channel while level 2 and above can be found when I do my zoom classes. I will be sure to mention the next time I have a zoom class on this channel and the website and all the social media pages. the level one is rather long to establish a good foundation which is why it is on the paid subscription side broken down into 13 chapters, the zoom sessions are usually 1 hour long and concentrate more on diagnostic and repairs of various components such as hv batteries, drive motors etc. thanks for watching!

If I may make a suggestion if you delayed the live feed over-lay on the charts by 5 seconds it would allow us to pause it to be able to read it before it gets obscured. Hope I explained this clearly.

  The injector cleaning ideally should be followed up with the end result. Especially the 2 injectors that weren't atomizing the fuel. Will those injectors be restored to atomization? Will the PCM adjust the injector width to compensate for incomplete atomization for an individual injector? Can the O2 sensor scope pattern be triggered to watch the stft on a cylinder with a streaming injector? (non-atomizing iow)
