Anyone ever have any luck cleaning a malfunctioning EGR Valve??

I got a CEL yesterday and the car was bucking a little under constant speed and light load.....thought the Coils might be on the way out but p0401 "Insufficient EGR Flow" showed up.......can you even clean it??:confused:

A new one is $100 or so and I'll probably just go that way unless someone offers hope with cleaning it!!:cool4:

A lot of views and no comments.....WEIRD??:cool:

Well......I pulled it off and it was stuck closed so I freed it up and cleaned it up!!

Put it back on and VOILA......throttle response is much better and surging and goofy performance is gone....WOW!! :banana2:

I was surprised at how clean it still was with all the miles I have on it!!:D

I guess the engine is still pretty healthy at 240K+ miles.....sure runs a bunch better!!:beer:

I have a new one coming anyway!!

I'd clean it with carb cleaner.

I did but it's CARBON and it's not soluble in anything so I just blew it out after soaking it with carb cleaner and it is working.....for now!!:D

Well folks......I installed the new EGR Valve and......WOW!!!:eek:

I would never have guessed it but the car is like new again.....great throttle response......rock solid idle (this has been a continuing problem)......minimal start-up "flare".......I cannot believe the old one was causing all the problems but it appears that it was!!:cool:

If my gas mileage around town improves that will convince me that the old EGR Valve was the culprit and I'll bet several of the IAC's I tossed out were not bad??:shake:

How long is the EGR Valve supposed to last anyway??:confused:

I believe it's for 8 years or 80k miles.

I would guess the lack of answers was 'cuz nobody knew. I sure didn't. Thanks for the info.

I've read some threads about EGR valves causing a condition called "trailer bucking". Suggested replacing the EGR valve. How difficult was it to pull the old one off?

It was quite easy......I was surprised!!:beer:

Big nut on exhaust tube.....2 vacuum connectors......1 electrical connector and 4 10MM bolts (2 on heat shield and 2 hold it on) and it falls into your hands!!:D

I recommend getting the Ford unit since it comes with the metal gasket and bolts.....others charge $20.00 for the silly gasket!!:eek:

Or just delete it all together :)

These cars run better with an active EGR Valve and are more efficient so I would never disable one!!:shake:

They are disabled in all vehicles at WOT so your performance WILL NOT IMPROVE by "deleting" it....PERIOD!!:rolleyes:
