Chevy Trailblazer misfire DIY diagnosis - step one - p0301 p0302 p0303 p0304 p0305 p0306
Here I have a Chevy Trailblazer with a P0302 - cylinder #2 misfire. I show you the basic troubleshooting steps that you can do that only require a code reader and a few hand tools. This procedure can be done regardless of which cylinder is misfiring. First, I swap the coil of the misfiring cylinder with another cylinder. At the same time, I swap the plug of the misfiring cylinder with another cylinder that is NOT the one that I swapped coils with. I then clear the codes and then run the engine. If the misfire moves to the cylinder that I swapped coils with, then I have a bad coil. If the misfire moves to the cylinder that I swapped plugs with, then I have a bad plug. If the misfire stays on the same cylinder, the problem lies elsewhere. Further steps will be shown in future videos. Big thanks to Bill (Kristis Dad) from trailvoy for donating the bad coil!!! UPDATE June 2013 - I know you can also unplug the coils with the engine running to isolate the cylinder. If you want to show that to these guys, how bout YOU make a video. When the average youtube user, who doesn't have much experience doing stuff like that, gets hurt, YOU can live with that on your conscience. I know I couldn't. SMFH.

2010 Subaru 2.5 Variable Valve Lift Solenoid and Switch Testing
This video is a great review of Section 2 "Switch Inputs" and Section 3 "Transistor drivers and Output Solenoids" in my eBook. On this system the intake valve lift is varied by two different cam lobes. A low lift lobe and a high lift lobe. I misspoke in the video calling this a variable valve timing or VTEC mechanism. This system does not vary cam timing, but it does vary intake valve lift.





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.

How to clean a throttle body and Idle air control valve (iac)
*** PLEASE READ *** In this video demonstration, I show how to get to, remove, clean, and replace the throttle body and idle air control motor (aka IAC) on a 4.2l ford motor. This procedure is the same for any fuel injected vehicle. * * * Check out my website krkvideos.com * * * The vans require removal of alot more stuff just to access the throttle body. A dirty IAC can cause a rough idle. A dirty throttle body can harm performance and cause rough engine operation. When the throttle body or iac is removed a new gasket must be used to properly seal the connection to the intake. GM idle air motors are generally mounted on the throttle body and can be cleaned without removal from the throttle body. This means one less gasket and a lesser chance of creating a vacuum leak. The ford throttle body had a note on it that said it was not to be cleaned because the coating on the throttle blade might be damaged. Thats fine for a new car but that has to be disregarded when working on something that has some miles on it. Subscribe to my channel. * * * Definitions: * * * MAF - Mass Air Flow sensor - Monitors the amount of air the engine is intaking. IAT - Intake Air Temperature - Measures the temperature of the air the engine is intaking. IAC - Idle air control - Controls the amount of air the engine is intaking while it is idling. Throttle body - Responsible for regulating flow of air into the engine as you press the gas pedal. TPS - Throttle position sensor - Tells the computer how far you are opening the blade in the throttle body so it can add more fuel to compensate the added air. * * * Visit krkvideos.com for more! * * * * * * Visit krkvideos.com for more! * * * * * * Visit krkvideos.com for more! * * *
