Throttle Body Cleaning - Dirty Throttle Body Symptoms and Problems
http://www.TrustMyMechanic.com (visit my site for TONS of free auto repair info)
Throttle body cleaning. Does your car idle rough, does the engine seem like it is trying to die when you are at a stop light, is the engine taking a little longer to start than normal?
You might have a dirty throttle body and that is something you can repair yourself. In this video we are cleaning the throttle body on a 2005 Ford F150 pick up truck with a 4.6 V8 engine.
Using just a wire brush and some throttle body cleaner made by BG, or you can use any throttle body cleaner made for throttle body service which is available at your local auto parts store.

"Common Throttle Body Symptoms and Problems"
What are the most common complaints I see in my auto repair shop that are related to a dirty throttle body?
1. Rough idle speed. We like to call this hunt and peck, like a chicken does when it is looking for food. The engine is trying to keep a steady idle speed but the carbon build up in the throttle body plates are not allowing it. So the engine is hunting for a steady idle speed, which causes the roughness you feel inside the vehicle.
2. Slower starts or extended starting periods. You might have to crank the engine over much longer than you used to. The engine might start and die, and you have to crank it again. These are pretty common complaints when there is a dirty throttle body issue.
3. Dies at stops. The engine is having a hard time keeping the idle speed high enough without dying. This complaint is worse with the air conditioner on, since there is more load on the engine with the A/C compressor on. A dirty throttle body will cause the engine to decrease the idle speed as the vehicle comes to a complete stop, and will eventually die. Restarting can take some time as in the extended crank complaint above.
This is a common complaint and the throttle body as well as the idle speed control motor should be cleaned periodically as part of regular scheduled maintenance.

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.
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.
How To Seafoam Your Vehicle
2 Can of Seafoam & 1 Can of Deep Creep - 1 can goes into your fuel tank and half of the other one goes into your oil and the other half goes through the brake Booster line. The Deep Creep is sprayed through the throttle body. Let the vehicle sit 15-20 mins. and start up and watch the smoke show. If you have no smoke your vehicle didn't have any carbon build up to clean off.

P0401 EGR Valve Port Cleaning
This is my DIY for clearing the CEL code P0401 (EGR Insufficient Flow) on a 98 Honda Prelude.
In cars with OBD2 if the EGR valve is restricted by carbon deposits it will detect that and throw a CEL. To get rid of that CEL you must clean out the carbon to allow flow.
After combustion occurs within the engine it creates Exhaust. Gas from the Exhaust straight from the engine is very bad for the air. The EGR valve recaptures that Exhaust and runs it through the combustion process again, which lowers the temperature of the fumes (Exhaust gas) and lowers the amount of pollution exiting into the atmosphere.
If you don't fix it you won't pass SMOG in California. You may experience rough idling and poor acceleration.
Get your "EGR port plugs" from Honda. They will have it.
Removing the injectors are important to allow clearance to the port plugs.
When you pull out the injectors you might as well clean them since they are out.
Slide hammers make pulling the port plugs out easily.
Drill with a bit the size of your tap. Drilling halfway through the port plug to should be enough distance to fully grab the port with the slide hammer.
If after you clean your ports and valve the CEL has not been cleared, you EGR valve maybe faulty and needs to be replaced.

Cleaning a Chevy Trailblazer throttle body I6 4.2
How to remove, clean, and reinstall the throttle body on a 4.2 inline 6 trailblazer.
This procedure is usually done if the engine idles rough or stalls with the a/c or defrost on AFTER the battery has been disconnected.
I also show an alternate method for resetting the pcm. (I found this tip in a post by mwfaith1971 on trailvoy)
Update 3/1/12 - Frequently asked questions:
Q- why do you pull those fuses?
A- to reset the pcm WITHOUT disconnecting the battery
Q- why don't you disconnect the battery?
A- that could potentially cause hvac actuator failure, moreso in the older ones like my 03...YOU can reset the pcm however you want to in yours:)
Q- can I pull the fuses and then clean the throttle body?
