Solving Engine Performance Issues (Part 1) - EricTheCarGuy
Visit me at: http://www.ericthecarguy.com/ See Part 2 http://www.youtube.com/watch?v=sAKwCzUE_9M Vacuum leaks http://www.youtube.com/watch?v=9CPqbaSgcok+ Voltage leaks http://www.youtube.com/watch?v=x-U9WqJfaJs Power Balance http://www.youtube.com/watch?v=bAOmUjAjNjE Compression testing http://www.youtube.com/watch?v=X_tbksFYhl4 Leak down testing http://www.youtube.com/watch?v=WgrfT0LFMhc&feature=relmfu I get a lot of questions via email and over at the forum about the steps to take when you encounter a performance issue like my Subaru's hesitation issue and I often feel like I sound like a broken record when I cover the basic steps that I cover when encountering a situation like that. My main point here is that if you have a performance problem and you're going to throw parts at the problem start with the basics before you to off and start replacing sensors that you suspect are a problem, if you don't have evidence of a faulty sensor then don't start there start with the simple tune up items and check for vacuum leaks and air leaks as I've shown here and I believe you'll have better results and save yourself some money in the process. In short the rule of KISS applies, Keep It Simple Stupid.

In Part 2 take questions from my students and really take this thing from start to finish on why I chose a particular test and how exactly to perform the test. I also show and discuss the compression waveforms that I took on this engine and why I came back to it being a fuel problem. These lecture videos (Part 2) will be in 3 segments and will be about 1 hour each. So there will be a ton of great information for those willing to learn and take your diagnostics to the next level.





P0325 Knock Sensor Diagnosis - EricTheCarGuy
Visit me at: http://www.ericthecarguy.com/ Wells website http://www.wellsve.com/ Wells YouTube (great videos I recommend you subscribe) http://www.youtube.com/user/markjhicks As you can see by the title this video covers the diagnosis and repair of a P0325 on my 1997 Subaru Legacy L model with 2.2L engine backed by an auto trans. I did have some trouble with the 'factory' diagnostic procedure but thankfully my friend Mark at Wells Electronics had a test that involved a voltage drop across the sensor that worked perfectly. I hope this video illustrates the import ants of understanding a circuit that you're diagnosing as opposed to just throwing parts at something, with a little time and effort you can do a proper diagnosis. --- Click below and Stay Dirty Visit me at EricTheCarGuy.com http://ericthecarguy.com/ Visit EricTheCarGuy Forum http://www.ericthecarguy.com/forum/default.aspx Visit my Facebook Page: http://www.facebook.com/EricTheCarGuy --- Stay dirty ETCG Due to factors beyond the control of EricTheCarGuy, it cannot guarantee against unauthorized modifications of this information, or improper use of this information.  EricTheCarGuy assumes no liability for property damage or injury incurred as a result of any of the information contained in this video. EricTheCarGuy recommends safe practices when working with power tools, automotive lifts, lifting tools, jack stands, electrical equipment, blunt instruments, chemicals, lubricants, or any other tools or equipment seen or implied in this video.  Due to factors beyond the control of EricTheCarGuy, no information contained in this video shall create any express or implied warranty or guarantee of any particular result.  Any injury, damage or loss that may result from improper use of these tools, equipment, or the information contained in this video is the sole responsibility of the user and not EricTheCarGuy.

Spark Plug Well Oil Leak Fix, Honda Accord - EricTheCarGuy
Spark Plug Well Oil Leak Fix, Honda Accord - EricTheCarGuy http://www.ericthecarguy.com/ I know I've promised this one for some time so here it is. If you have this problem I recommend replacing the seals in the valve cover first and then coming back to recheck for oil in the spark plug wells in about a month or so, if you find oil then I recommend performing this procedure. I can't stress enough how important it is to make sure everything is lined up correctly when you reinstall the rocker assembly, bad things can happen if you don't. --- Click below and Stay Dirty Visit me at EricTheCarGuy.com http://ericthecarguy.com/ Visit EricTheCarGuy Forum http://www.ericthecarguy.com/forum/default.aspx Visit my Facebook Page: http://www.facebook.com/EricTheCarGuy --- ETCG Due to factors beyond the control of EricTheCarGuy, it cannot guarantee against unauthorized modifications of this information, or improper use of this information.  EricTheCarGuy assumes no liability for property damage or injury incurred as a result of any of the information contained in this video. EricTheCarGuy recommends safe practices when working with power tools, automotive lifts, lifting tools, jack stands, electrical equipment, blunt instruments, chemicals, lubricants, or any other tools or equipment seen or implied in this video.  Due to factors beyond the control of EricTheCarGuy, no information contained in this video shall create any express or implied warranty or guarantee of any particular result.  Any injury, damage or loss that may result from improper use of these tools, equipment, or the information contained in this video is the sole responsibility of the user and not EricTheCarGuy.





How To Replace Brake Fluid - EricTheCarGuy
As I said in the video I've been asked about this video for some time and I was happy to get the opportunity to make it. Now that I think about it however I did not address ABS systems in this video however the Subaru used does have ABS. For the most part, you can replace the brake fluid and not have to worry about the ABS, however in some cases you might need to bleed the system with a scan tool in order to get the brakes to work properly. Be sure to check the service manual of the vehicle you're working on before committing to bleeding at the wheels. If you're just removing the fluid in the master cylinder, you should not have to worry about the ABS at all. If you're having brake problems, check out this article I wrote on handling brake problems: http://www.ericthecarguy.com/faq/solving-brake-problems The best place for answers to your automotive questions: http://www.ericthecarguy.com Facebook: https://www.facebook.com/EricTheCarGuy?fref=ts Twitter: https://twitter.com/EricTheCarGuy Google+: https://plus.google.com/100195180196698058780/posts Information on Premium Membership: https://www.ericthecarguy.com/premium-content-streaming-etcg-content Stay Dirty ETCG Due to factors beyond the control of EricTheCarGuy, it cannot guarantee against unauthorized modifications of this information, or improper use of this information.  EricTheCarGuy assumes no liability for property damage or injury incurred as a result of any of the information contained in this video. EricTheCarGuy recommends safe practices when working with power tools, automotive lifts, lifting tools, jack stands, electrical equipment, blunt instruments, chemicals, lubricants, or any other tools or equipment seen or implied in this video.  Due to factors beyond the control of EricTheCarGuy, no information contained in this video shall create any express or implied warranty or guarantee of any particular result.  Any injury, damage or loss that may result from improper use of these tools, equipment, or the information contained in this video is the sole responsibility of the user and not EricTheCarGuy.





Compression Testing and What You Can Learn From It - EricTheCarGuy
Compression Testing and What You Can Learn From It - EricTheCarGuy Here is a video on performing a compression test on an engine to assess it's mechanical condition. An engines ability to compress air and fuel is directly proportional to it's performance since an engine is nothing more than an air compressor once you take away all the controls. A compression test is a good general test that will give you an idea of the engine's overall health but it does not give specific information on what the problem is should there be one, for that a "leak down test" would be required, here is a link to that video. http://www.youtube.com/watch?v=WgrfT0LFMhc However if you find yourself looking for the source of a performance problem with an engine, this is a great place to start. This test is often overlooked in favor of looking at the fuel or ignition system, I think that's a mistake, if an engine can't perform mechanically no amount of electronics will make that better. Recently, I hit the 500 subscriber mark and I'd like to thank all of my subscribers past, present, and hopefully in the future for that. I enjoy making these videos and the fact that you seem to like watching them means a lot to me. So, thanks for subscribing, rating, and commenting, those little contributions make it all worth while. --- Click below and Stay Dirty Visit me at EricTheCarGuy.com http://ericthecarguy.com/ Visit EricTheCarGuy Forum http://www.ericthecarguy.com/forum/default.aspx Visit my Facebook Page: http://www.facebook.com/EricTheCarGuy --- Also see the video I did, "Octane Ratings and the 4 Stroke Engine Cycle" for more information on how compression works and why it is important. http://www.youtube.com/watch?v=8VWEwEveGTQ Thanks for watching and stay dirty ETCG Due to factors beyond the control of EricTheCarGuy, it cannot guarantee against unauthorized modifications of this information, or improper use of this information.  EricTheCarGuy assumes no liability for property damage or injury incurred as a result of any of the information contained in this video. EricTheCarGuy recommends safe practices when working with power tools, automotive lifts, lifting tools, jack stands, electrical equipment, blunt instruments, chemicals, lubricants, or any other tools or equipment seen or implied in this video.  Due to factors beyond the control of EricTheCarGuy, no information contained in this video shall create any express or implied warranty or guarantee of any particular result.  Any injury, damage or loss that may result from improper use of these tools, equipment, or the information contained in this video is the sole responsibility of the user and not EricTheCarGuy.
