Secret of Engine Problem Diagnosis- Fuel Trims Pt.1
One of the best techniques for diagnosing check engine lights or engine
problems especially for lean or rich engine diagnostic trouble codes
(DTC's) is to examine and interpret Fuel Trim data. This video will help
the home mechanic learn how to use a very basic scan tool to develop
powerful diagnostic capabilities and prevent changing parts unnecessarily.
Fuel Pressure Regulator Repair
In my first video of 2013 I show how to replace the fuel pressure regulator
on my Ford Probe. The procedure is pretty much the same for any car. Thanks

How to Properly Perform a Fuel System Cleaning
What I am showing you is the proper way to clean the fuel system of your
vehicle. The vehicle in this video is a 1998 Saturn SL2 with a 1.9L DOHC
engine. It has over 177K miles and is the second time a fuel system
cleaning will have been performed. The last time, I had it done
professionally at a local service center. After 20,000 miles, thought I
would figure out how to do it myself and cheaper.
Items you will need are:
- Seafoam Motor Treatment (or equivalent product)
- Self built intake cleaning hose
Components of fuel system cleaning hose:
- 4ft of 3/8"ID Vinyl Tubing
- 1ft of 1/4"OD Polyethylene Tubing
- 1/2" hose mender
- 3/8" x 1/4" barb connector
- 1/4"x1/8" connector
- 1/4" x 1/8" needle valve
All these items you should be able to find at the local hardware or
plumbing shop. This is just a prototype I have created and will be
refining the design as I go along.
Take the needle valve and attach the 1/4" tubing to one end and the 3/8"
tubing to the other. Use the 1/2" hose mender at the end of the 3/8" tubing
(You will have to force it on because mender is a lot bigger than the
inside diameter of the tubing) as the attachment point of the vacuum line.
I will be using Seafoam Motor Treatment for this video. There are other
similar products out there, but this is the one I have chosen. You will
also need a throttle body cleaner as well. Both of these can be found at
your local auto parts store.
1. take the Seafoam cleaner and separate it into 3 equal parts, or since it
is a 16 oz bottle of this particular cleaner, I chose to separate it this
1. 5oz. for the fuel
2. 5oz. for the oil
3. 6oz. for the intake cleaning.
2. Disconnect vacuum hose from the brake Booster. This is the big round drum looking
thing on the driver side at the rear of the engine compartment.
3. Take the intake cleaner hose you have just put together and attach the
1/2" hose mender to the vacuum line.
4. Take 5oz. and add to the fuel tank. Use a funnel to help keep the
cleaner off vehicle paint.
5. Remove oil cap and pour the other 5oz. in with the oil.
a. This will clean the lower end of the engine.
6. Take the bottle with the remaining cleaner fluid and poke a hole in the
top so that the hose 1/4" hose can fit through.
7. Somehow have it so it is hanging above the engine and that the 3/8"
tubing connected to the vacuum line is straight.
8. Make sure the needle valve is closed all the way and start the vehicle.
9. While running, slowly open the valve and allow a steady stream of
cleaner to enter the engine. Don't open the valve too quickly or you will
let too much cleaner in and may stall the engine.
10. Once the can is drained, turn off vehicle and let it sit for between
a. This will "Hot-soak" the engine and break up the carbon and
tarnish build up.
11. Reattach the vacuum line to the brake Booster. Very important or your engine will
run at higher RPM's and you may not have brakes.
12. During the wait, you can clean the throttle body by removing the intake
hose from your air filter exposing the butterfly valve. Open this valve
and spray in the cleaner. Make sure all surfaces are covered and let this
cleaner sit and break up the build up on and behind the butterfly valve.
a. DO NOT perform this step if you have a Mass airflow sensor.
These are very delicate sensors and expensive to replace. Do not messed
b. If you want to be more thorough, take a cloth or some type
of swab and manually clean off the build up that way it does not get sucked
into the engine.
13. Reattach the intake hose
14. After the wait, start the engine and rev the engine to between
2000-3000 RPM to blow the buildup and cleaner out through the Exhaust. The engine is going to start rough so
make sure you are ready to step on the gas to keep it running.
15. When you see that the smoke is becoming lighter, drive it for about 20
minutes to finish the process of cleaning.
16. You may see a check engine light come on, this is normal. Have someone
scan it to be sure and then erase the codes. It will most likely show
cylinder misfire and O2 sensor malfunction codes. If it is something else
then investigate further.
You have completed a complete fuel system cleaning. It is recommended on
the bottle that you perform this every 2000-5000 miles. I would recommend
every other oil change, or for those that drive a lot, at least twice a
year. This helps maintain horsepower, and fuel
If you have not done this procedure before, it is probably a very good idea
to have this done, either professionally or by yourself.

today, you do so at your own risk.
Clean Fuel Injectors Means Better Gas Mileage!
Have you ever wondered how a fuel injector worked? David Rogers shows how
clean fuel injectors can lead to a more efficient burn, meaning better gas
mileage and lower emissions! (He also lights some stuff on fire) The
secret to a clean fuel line is MotorVac, a system that cleans your entire
system, from injectors to the catalytic converter.
