How To Clean The EGR Valve On A GMC Safari Vortec V6 Engine
Here is how to clean the EGR (Exhaust
gas recirculation) valve on a GMC Safari Vortec V6 engine. If your engine
started running really rough all of a sudden, your EGR valve may be stuck
open. It's easy to remove and clean up. It is a good idea to install an
EGR valve gasket with a filter in it to prevent future carbon buildup.
Here is a link to a video I made showing the gasket:
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

How to fix p0401 egr code on 3.1 v6
Don't go out and buy a new EGR valve for $100. Heres how to fix it
yourself. If you have the code P0401 EGR flow insufficient, just clean the
passage way. Using a wire coat hanger or piece of flexible yet strong wire
and throttle body cleaner you can clean this yourself. Afterwards make sure
to clean out your throttle body of all the crud deposits. This engine is in
my 98 Buick century, along with Chevy Malibu, Chevy Lumina, Grand Am, Grand
prix. Thanks for watching
How to Seafoam your vehicle (Also called Top Engine Clean)
This is a carbon deposit cleaner that when used can help eliminate the
carbon deposits that build up in the top end of your engine block. I
perform this about every 15,000 miles on my own vehicle.
Steps to seafoaming:
1. Bring your vehicle up to normal operation temperature
2. Separate seafoam canister into 3 equal parts (one will be for sucking
through a pvc line or brakeBooster
line, one for gas tank, and one for putting in the oil filler cap)
3. Locate the PVC valve that runs through the intake manifold, for this is
where you will initially suck 1/3 of the seafoam canister through.
(If PVC is non accessible then you can use your brake Booster line in the same manner.)
4. Once engine is at normal operational temperature, have another person
sit in the drive seat and bring the engine RPM up to around 1500.
5. Pull your PVC off (or brake Booster line) and start slowly sucking 1/3 of
the seafoam in through either of these locations. Be cautious & steady
handed, you don't want to stall the engine out.
6. Once you've sucked all of the 1/3 portion up turn the engine off &
replace pvc or brake Booster to its
7. Once engine is off, unscrew your Oil Filler cap & pour 1/3 of the
seafoam in as if it were oil.
8. Unscrew gas cap and put the remaining 1/3 seafoam in.
9. Leave the car alone for 15 minutes.
10. Come back to the car and start it up, let it idle for about 10-15
seconds and then BRING ENGINE RPMS TO A STEADY 2000-3000RPM for no more
than a couple minutes.
(major revving or fluctuation can knock carbon deposits loose so please
keep a steady foot)
11. Once this is complete, take your car for a 10-15 mile drive, while
doing so make sure to bring the engine through its total rev band spectrum
to make sure all the carbon deposits have been cleaned out.
12. Once the drive is complete, bring the car back home.
13. CHANGE YOUR OIL & FILTER & SPARKPLUGS WITH KNOWN GOOD OEM SPEC PARTS.
(The reasoning behind this is that the seafoam lowers the viscosity of your
oil, thus weakening its ability to control wear on your engines major
mating surfaces and your plugs get buggered up with carbon after this
tuneup due to the carbon coming loose during the tuneup.. So an Oil/Filter
change & Spark Plugs are a must after seafoaming is complete
14. Tune Up is complete!
