ASE A8 Engine performance introduction to fuel systems Day 1 Slides 20-30 of about 7200 slides.
South Florida Technical Training (SFTEC) Has been successfully training technicians to pass ASE certifications for over 12 years. We have trained hundreds of students to pass their ASE certification test. We are currently putting together our online version of our training program. We are looking for a new location to offer our hands on classes.
For the last 12 years we have been teaching the classes using hand outs and power points. There are about 60 slides per class day. I have been recording the classes and making videos for years and am putting that together with our videos and questions to make the online program. This video is just 10 slides of the 60 slides for engine performance day 1 Fuel system. The engine performance fuel class has over 720 Slides and 100’s of videos. Everything is done in short format and changes on average every 60 seconds.
The questions below are examples of the questions we ask on these 10 slides.

    You may have to have the code cleared a few times, but the best thing to do is to put the new part in turn your key on. Do not start the vehicle press your accelerator all the way down to the floor and hold it then let it slowly off and then do it again and hold it and then let it off and then start the car and then shut it off. You may have to go to the shop so they can clear the code a few times, but then You just need to keep Driving it and clear the codes a few times which if you take it to Shop to get done, they should do it for you, whatever you do, don’t keep buying new petals to put in just keep clearing the coat truck. The vehicle has to learn that it’s not jacked up anymore. I don’t know why the codes are so hard to clear on this one, but it is a pain in the ass once you finally get it cleared it’ll be fine, it shouldn’t take but at least

      A v belt is shaped like a V and a serpentine belt is flat with 3-10 or more very small v groves cut in it. The serpentine belt has more surface area making it better at not slipping.

    I am having this same exact issue on my daughters 2012 Equinox with the 2.4L EcoTec. I replaced the pedal and throttle body. What's bizarre is that I can reset it, and then the only way it will come back on is when you press past 50% throttle. Should I be looking at the ECM connectors and/or replace the ECM?

  • @brandonlecrone6838
    @brandonlecrone6838 Місяць тому

    Been dealing with this on 15 Chevy Spark for the past two years. If replacing the pedal doesn't fix the problem, will it do any damage to the engine (or whatever) to just live with it and reset the code when it pops up every few months?
