O2 Sensor Basics - EricTheCarGuy
This will be the beginning of a series that I'm going to do on computer controlled systems. I've had quite a bit of response to the check engine light video and I think this is the next logical step. I've covered the basic operation of an O2 or oxygen sensor as the basis for closed loop operation. This will probably not be the last time I cover information on O2 sensors, there is so much more to these than meets the eye.

Homemade Fuel Injector Cleaner - How To
There has been a follow up to this video and it is located here. http://www.youtube.com/watch?v=JRaoCtehGHk.
This project was inspired by another Youtube member. http://www.youtube.com/watch?v=3mnA0cnXckg&feature=channel_video_title
I picked up a set of used Blue Max 1650's and wanted to clean them before installation sooooo.........
I followed the video in the link with minor adjustments. When using the larger coupler listed in the video, I could not even get the threads to drill out. I had a smaller coupler laying in the garage that worked for my injectors. I also used the drill bit one step above the 27/64 listed in the link. This is 7/16 and just seem to be easier to handle while maintaining a good seal.
Another discovery along the way is the size O-rings that you could use for upper seals. If your injectors have good seals, Why chance ripping them. A #11 O-ring serves for a great base O-ring on the top side of the injector. The #78 serves for an outstanding upper O-ring for the upper seals. You will see this demonstrated in the cleaning video.
One last VERY IMPORTANT note is YOU MUST USE A AA BATTERY FOR THE SWITCH. I started out using a AAA and had great results on the 950's but the AAA would not open the 1650's under pressure. After adding a AA everything worked perfect.
The injectors did measure out to be 2.3 ohms.
Quick Tip-Throttle Cleaning - EricTheCarGuy
This one goes out to BowlingBallOut who posted a question about a sticky throttle on his Saturn. It was a great question so I decided to make this video in response to it. There are many different configurations of throttle assemblies but for the most part if you have a throttle that is sticking you might be able to fix it using the procedures in this video. I am aware you may not able to purchase spray throttle cleaner in some states now but I'm sure they have some alternative available at your local parts store.

How To Clean a Mass Air Flow Sensor (MAF)
Here I demonstrate the simple steps involved with cleaning your mass airflow sensor. In this particular case I was troubleshooting a rough idle on a 2006 Chevy Colorado 3.5, but these steps can work for almost any vehicle. If you have any questions feel free to post them and I will do my best to help!
How to find a misfire without a scanner 3
Scanners are great tools, but sometimes they aren't any help. That's when understanding the system, and how to test it is all you have. Here are some ways to find the problem
DIY Fuel Injector Cleaning & Repair
This is the end result of a few hours of work and $60 because I didn't have a 1/4" NPT tap in any of my kits. I could have done this for less-than $40. The BG products were donated to the cause.
Tech info:
The REASON you want to use 20 PSI is precisely because of how peak-hold type injectors work. The injector signal sends a 4v spike to open a peak-hold type injector quickly, then maintains its open condition with only 1 volt. Really, it's a current thing and there's a longer explanation, but that's it in a nutshell. When you put the injector in its operating pressure, it takes more than a AA battery to open it, but you don't want to sustain that much current with a momentary switch and your expensive injectors. This isn't in the video because this warning wouldn't be as clear. Unless you can simulate the injector pulse precisely, don't try it. 1.5v is enough to open it below its operating pressure. If you open it and THEN apply pressure, you can flow as much pressure as you can throw at it.
I don't discourage anyone from getting their injectors professionally cleaned and balanced, but in my case, I didn't feel that was necessary.
In my first video, I thanked the seller for these injectors and happy to know I got a great deal on high quality parts. My gratitude is even greater because I had problems with them. It gave me an opportunity to help others troubleshoot these kinds of problems when purchasing used parts. A different idiot might have blamed the seller for peddling crap, demanding their money back... but that would only be because they didn't even know what they were looking at.
This particular idiot knows what high quality parts RC injectors are and how to clean 'em. $250 + $60 still means I saved about $150 on a brand new set. We all benefit because I bought these and I'm grateful! Let the good times roll.
Picking the Honda Civic Ignition
This is not for illegal purposes! This is for locksport only!
This is me picking the door lock and then the ignition switch to a 2002 Honda Civic. First I pick the ignition without the key near the sensor. The immobilizer check fails and the engine will not start. Then I turn the switch again with the correct key held close to the sensor to fool the electronics. You can see the security light shut off and the engine start like a charm.
