FYI, the code was:
P0401 - EGR Flow Insufficient.

Using Auto-RX...EGR Check Engine Light Went Away

I can easily ignore it. As can anyone who understands how EGR works. The only thing looking ridiculous is you. I don't know what you do for a living but it for sure doesn't have anything to do with repairing cars. It appears the same is true with the guy who sells this stuff. It may well have some cleaning action since it's an ester but I can get that for lots cheaper in a good oil. At any rate it had zero to do with his EGR ODB fault.
I am at the end of an ARX cleaning on one car and beginning on another.At this point i can neither vouch for nor condemn the product,time will tell but IMHO its worth a fair shot.The only possible explanation for the EGR flow improving is if it were an older vacuum operated unit and the engine was now pulling more vacuum because of improved compression,if there were low vacuum the valve may not open completely.a little far out theory i know but thats all i can think of,as oil cannot and will not get into the passages it could only be the valve being opened more from another source.
Let me guess. you put ARX in your crankcase only and it fixed your slipping transmission. right? because that would then be analagous to ARX cleaning out the EGR. oh, and your blatant paranoia is hilarious.
This is basically what you are saying. I put AutoRX and it cleaned my catalytic convertor. Not as much of a stretch, but there is no fluid that gets to the EGR valve. Unburned fuel vapor, oil vapor, sure. But to say that oil vapor that is 1/16 ARX cleaned baked-on carbon in 350 miles in an area that doesn’t get oil flow, using the vapor of a fluid that takes 1500 miles to clean well lubricated areas that get constant oil flow, and even then isn’t a miracle worker, is a little hard to believe. Could it happen, sure, but I wouldn’t bet the family farm on it. If you soaked an EGR valve in it, maybe, vacuum change, maybe.

Who knows what happened, the EGR system has many diffent things effecting it. Maybe the Autorx increased oil flow which in turn lowered engine temps, thus helping the EGR system. There are too many possibilties and too many variables to say it had no effect without a doubt. I'm not saying the Autorx fixed the EGR system, only that it's possible as a helping factor. Theory is one thing, but in the absence of proof of what happened to the EGR/Engine light, you can't rule out the possible fixes.
Improved combustion efficiency is the only thing I can see that could somehow make the light go off. As I said, mine went off for a few hundred miles and came back on (I had the same code on my Grand Marquis). The only way to get it to completely go off and stay off was to physically clean out the ports.
Shelby,
EGR sensors are not located in the oil circulation areas of an engine. I, as well as others, have already stated this. Also, the EGR plugging is due to "sludge" deposits from exhaust gases (NOx), NOT oil vapors. For example, my parent's 92 Crown Vic (4.6) does not have the EGR code (yet) and it has visible sludge in the engine, where as my 95 Grand Marquis (4.6) did have the EGR code (for 6 years) but the engine insides are visibly clean.
And before I get bashed, I have a bottle of Auto-RX waiting to be used, and that's how I'll prove to myself whether it is worth it.

I don't know what Shelby's problem is but I'm sure he's a decent enough guy. Most people are so here's my final word on RX. I've read the patent and the chemistry seems valid. It likely does do some cleaning but so will a fill of Redline. What I can't get past is how many on this board are so quick to pound on other products that have the same level of "success" while ascribing all sorts of miracles to this additive. It also gets old to hear the maker of this syrup continually pushing the typical snake oil kind of dogma. Especially when it makes no sense like in this EGR case. Makes one wonder how much he really knows about things automotive.
I'm still sticking to my view that for the price this product should have a better success rate. If it really worked as well as claimed it shouldn't be so hit or miss. I see page after page of the same subjective and acedotal "proof " common to lots of additives. OK, it works sometimes and with varying degrees of effectivness. So what? How is that different from other additives except for the high price? Myself, if I'm going to pay that kind of money I want something with a better track record. If it's chemistry is as legit as claimed why doesn't it have one? Since when is this kind of thing rocket science?
Not to mention the usual points about these things: why can't this stuff be bought anywhere other than online, why don't the oil companies or auto makers use it, why is this guy (figuratively) churning out batches in his basement instead of lying on a beach somewhere, on and on.
That's my final word on the matter. I'm not a troll or a competitor and I'm not "hatin" on RX. I just fail to see any real proof it lives up to the hype. It certainly didn't for me. And I don't see why most other additives get skewered here while this stuff skates. Then again there is so much conflicting information and differing opinion on this board in general by people who may or may not be qualified to offer facts it's no wonder others leave as confused as when they arrived.

Maybe the light did actually burn out.
Nope. Checked it. Still working.
Socom, I'm usually not a bomb-thrower, but I'm no shrinking violet either. I don't know you from Adam, and I have no reason to doubt you.
But I see that all six of your posts are on two threads and each post has ARX in the crosshairs.
I see the beginnings of a trend there...
SOCOM Auto-Rx works if you work it.We have way to many repeat buyers for your disatisfaction to carry merit. Lubrizoil (they make most of the additives used by the major oil company's)wanted Auto-Rx at a price that was unacceptable. A major oil company has tried to make 1/4 of an ounce of Auto-Rx replace several additives (this ratio can't work)thats why we have not sold company to oil oem's.
Auto-Rx will clean sensors as it is cleanong metal, it does not directly influence a egr valve, however since cleaning takes a load off the engine, it seems reasonable to say it may help this unit.

I am buying into the combustion efficiency factor and increase in vacuum that improved the workability of the EGR valve. Of coarse ARX will not directly effect the EGR valve. However quite likely the indirect effect.
Mr. Incredible, any seat of the pants improvement in your unit?

The person who suggested it said that was the old EGR design and the original poster has a 98 and a 99. Please stop trying to attribute everything to ARX. And perhaps ARX is the only thing SOCOM has tried and felt the need to post about. Perhaps he/she doesnt use GC, or LC.
<<the result of too much oil contact.
