    Dan love your videos, I used to be very good at diagnosing and fixing problems with pretty much anything from cars to computers, electronics, been in the tech field all my life. Was injuried in a accident couple years ago and suffered a serious concussion and orthopedic issues that are permanent. I watch your videos and listen to your ways of diagnosis and repair to help me with my recovery thanks and continue your way of education thx

    People need to be educated that’s a fault code is a symptom and not a diagnosis. Good job as always 👍🏻

    A quick check would have been to simply unplug the maf sensor. The engine would have ran on the default fuel table using tps and rpm points for fueling. I know Dan knows that. Just mentioning it for those who don't have a scope.

    Another excellent case study. As I follow along I often pause the video and consider what I would do next. Although my first guess on listening to the engine was a plugged exhaust, the data pointed right at the MAF. As usual I didn't think of the other important cause, reduced fuel delivery from a weak pump, exposed when demand increases. In a way, this presentation is a crude reciprocal of a vac leak, in this case going lean at WOT, with secondary compensation. Thank you for walking us through another useful learning experience.

    great job again. Diesel engines with EDC have the same issues,for example when no have turbo boost and no have dtc code, first check is the condition of MAP sensor.I fixed a lot of cars just after i clean the carbons and oil inside them. bravo Dan, continue with great videos. This is a very good example when one technician know the thing on the DNA level 😉. It is very important to know how to diagnose with scope.👍🏻👏

    Excellent video Dan, one note to viewers, this is a clear case of uneven revving around 4000 rpm, newer engines, for example VAG engines are rev limited at full throttle while you’re parked or standing still. Don’t confuse the two situations. I have a 1.4TSI which sticks to 3500 rpm at full throttle, but even running.

    That takes me back, too many parts fitters these days rely on fault codes. I had a 2.0 TFSi that was showing all sorts of boost fault codes. On the Skoda 2.0 TFSi the air filter box is held on by big rubber bungs. These bungs can become displaced when refitting the air filter cover and get sucked into the turbo! A really bad design fault. Once the chewed up bits of rubber were removed from the turbo, no more boost fault codes!

    Hi sorry Dan ! No comma from me for a long time . My peugeot 5008 1.6 rudimentary is running on 3 injectors and because I have used my downloaded version of the peugeot DIAGBOX windows 7 software too many times to clear the fault codes at various repair stages , now I am getting error messages . The whole engine was overhauled(new camshaft , skimmed old cylinder head , new injector seals and sleeves, new gasket , new crankshaft magnet ring , water pump all professionally fitted and torqued ) . My question is if either I programme the non firing injector with my software and if it works then also if there are still error messages popping up because of the fault code storing memory is full , I will have to take the car to the peugeot dealers to remap( whole software update ) the ecu any any other things need to be done . Please kindly advice me if this is the way to go ? Thank you so much and I wish you late Christmas greetings and a very happy new year . I have been ill since April this year and could not do much with my car . Just waiting to get better myself and for a better weather !!

    First off awesome job, I wanted to say that the test of the 02 sensor heater circuit was great. Sometimes I forget that wideband sensors use them too. I liked the use of the scope in circuit testing the maf, I personally like using the calculated engine load % to find dirty mafs. Toyota needs 90% minimum on wide open throttle. Then I would break out the scope. Anyway! Great job!
