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. Tips: 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.

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: http://youtu.be/cBUds9Nypmc





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 original housing. 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!

The race pipe and EGR cooler delete kit together ran me exactly $169.01





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

Here is how to test code P0401 and the DPFE sensor. Sure, the DPFE has a high failure rate, but do we "throw" the part at it, or do we test it to be sure it's actually failed. AND, this is a great way to confirm the repair to prevent a "come back"
