Misfire Case Study (1999 Honda Accord)
Visit my website, www.scannerdanner.com for more about my eBook and lectures. Visit http://www.youtube.com/channel/UCs2NZ_wQFDFvV0QOhoZgASA to watch Part 2 of this video. 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.

1996 Ford F-150 No Start with ScannerDanner-EricTheCarGuy
1996 Ford F-150 No Start with ScannerDanner-EricTheCarGuy ScannerDanner and EricTheCarGuy are back again this time solving a no start condition on a 1994 Ford F-150. This time I wouldn't let him use his fancy expensive scanner and to be honest it was no problem for ScannerDanner because he understands the fundamentals. It's really great to work with ScannerDanner because he knows so much about these systems and how they operate, I learn something every time we work together. So please enjoy this no start diagnosis with nothing more than a spark tester, a DVOM, and a test light.

1996 Jeep No Start Case Study Part I

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. If you have questions about your own engine performance issues head over to my website and either ask the search function or ask the forum, we'd be happy to help. http://www.ericthecarguy.com/forum/default.aspx --- 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.

How To Perform a Parasitic Draw Test - EricTheCarGuy
http://www.ericthecarguy.com/ This video has been a long timing coming and is one of the most requested things I get is about batteries going dead overnight so I'm very happy to finally bring you this video about the process of finding a parasitic draw which is a small drain on a battery above 50ma when the vehicle is shut off. Once you find the right fuse(s) the next step is to trace the components involved in that circuit till you find the source of the draw, you first start with a wiring diagram to give you an idea of where to start looking and then start unplugging things in that circuit to isolate the cause, it's quite scientific really a simple process of elimination. Here is a link to BBB's site that you can use to look up wiring diagrams for your application. http://www.bbbind.com/tech_database.html Good luck and if you have anymore questions check the database on my website and if you don't find what you're looking for there then post your question to my forum, here's a link. http://www.ericthecarguy.com/forum/default.aspx --- 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 --- Be safe, have fun, 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.
