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.
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.

Leak down testing
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.

Hyundai Elantra 4g63 Shortblock Assembly
HOLD ON TIGHT! HERE WE GO!
We begin the blueprint and assembly on my 1992 Hyundai Elantra's
bastardized 4g63. The parts used in this are from a mash of different
brands and models outside of the typical 2.0L 4g63, but the specs and
standards I am following for its assembly are for the 2.0L DOHC.
If you want to follow along in your service manual to verify what I've done
here in this video, the processes we cover here detail pages 11C-95 through
11C-105 of the 1g Overhaul manual. I would prefer you not rip them from
the binding and throw them away, relying only on this video for
instruction... but rather use this video as a motivational guide, and as a
demonstration of the techniques involved in those sections.
You gotta do the cooking by the book.
I never had any intention of making instructional videos on this particular
car, but after it blew up I slowly realized it's actually a better case
study for how a 4g63 ticks than anything else in my driveway. There are
several reasons for this. One being that it's a mix of parts that
shouldn't be bolted together, and the other is that many of you watching my
videos aren't trying to build a 600hp engine out of aftermarket parts.
You're trying to put back together what used to be your daily driver. This
car covers those bases. Don't think for a second I won't go through this
same trouble and level of detail for the GSX. I will. When I do, having
this information in this video will give you a better understanding on how
and why I do things the way I do when I get there.
This was the shortest I could condense this video. I've never uploaded a
video this long, and I hope I never have to do it again. It took a month
to create on cutting-edge equipment, 16 hours to export, and 9 hours for
YouTube to process. My script for the voiceover is 6 times longer than the
whole script for the movie Pootie Tang. 6 times. Longer. Than a
How To Quick Clean a Throttle Body
Ecotec 2.4L - Removing the top engine cover,
- Quick clean on the throttle body,
- Reinstall top cover
Car used in this video 2008 Malibu.
This procedure cannot be done like this on newer electronically controlled
throttle systems; otherwise, it may require re-calibration of the ECU
If you DO NOT have a manually controlled linkage cable from the accelerator
pedal on your vehicle, DO NOT attempt this procedure.

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
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.

DIY Testing & build EFI Fuel Injector cleaner
In this video I detail some quick tests and some not-so-quick fixes.
A dirty or stuck injector is not usually a fatal problem for the part. You
can clean injectors yourself with a little ingenuity, or use an injector
cleaning service. With the method I'm using, you won't get a sheet that
measures how much fluid is flowing, but if you use the right solvent you
can at least remove whatever is blocking it so that it can flow like it did
when it was new.
So the journey begins.
Many of you have seen this one before. I apologize if bringing it back

Learn to test and analyze automotive fuel injector circuits from a wiring
diagram perspective. Fuel injectors are attached to the fuel rail. It is
very time consuming to detect and prove a clogged fuel injector. The
technician needs to disassemble the fuel rail, de-activate the fuel pump
and perform lengthy tests to prove the fault. However, there is another
way. Using current ramping techniques the technician is able to prove the
fuel injector without any disassembly at all. Get the scoop here and save
