How To: EGR Removal and Cleaning for Rough Idle Fix

I did take the clamp off but it still wouldn't budge. I could only move it a little bit but it wouldn't come off.

That rubber tube gets stuck on there pretty darn good. Just make sure the clamp is loosened enough and give it a yank. When I put the CAI in the P5 I had the same issue with the stock intake. Just pull from the driver side and wiggle it a bit, it'll come off :)

Yeah, its cracked anyway so its needs to come off.

I found one on ebay for 30 bucks.
 
i cleaned mine today...i only decided to clean it because when it's cold as **** outside at 5am my car idles at 3,000 rpm for like a couple of mins....so we will see how it does tomorrow morning
 
^ my car doesn't quite idle up that high, but even in WARM weather it idles high for a good 30 seconds when I first start her up in the morning...

kind of annoying, but it effectively blows out all of the oil from the compression chambers
 
Hahaha why would you do it yourself if it's covered under an unlimited warranty. In my old 02 Protege would also stall out when I would idle. It would cost $300 plus to get it fixed at a garage or have to pull it apart myself and clean it like most of you but I took it to Mazda and it's covered under an unlimited warranty. The EGR is faulty in the protege. Therefore, they fix it or replace it if needed, FOR FREE :)

Not sure if the warranty stuff is different in the USA but that's what it is here in Canada haha, go check it out.

My rough idle is back...

Does anyone know what phone number to call to see if US cars are covered under this EGR "unlimited" warranty? I'm sure calling a dealership will have mixed results, might be best to call the company...

I'd just go right to your nearest Mazda dealer. I never bought mine new from them or anything I've never dealt with Mazda directly until this point. I just called and they ran my VIN number and said yes come in whenever you can it will be fixed free of charge. I'd do that before you do anything :)

and yes I even had to re-assure myself on the "unlimited" part of it. It's a faulty part so they do cover it forever no matter if the car has 1,000,000 miles on it.

Hey guys, I just wanted to write up my experience...

For about 2 years, my car's performance gradually decreased. It was pretty gradual, and so I didn't really notice it. After a couple of mods made no difference in performance even though they should have yielded at least 25-30hp gains, I became suspicious, but didn't have time to check it out in depth. I checked to make sure there were no boost leaks in the intake plumbing, but it was all fine.

About 2 months ago I threw a CEL. I took it to the Mazda stealership, who said it was EGR code and bad coils. Apparently, my EGR was stuck open!! It was causing a boost leak. Where I should have been seeing 8psi, I was only getting around 4psi. I replaced my EGR with a used cleaned unit and replaced the coils. What a difference!! The car is a beast now! (thumb)

The funny thing is, it was running with the EGR stuck open for around 30k miles without throwing the CEL. So for those with "mysterious" boost leakage, the EGR is worth checking out even if you have no CELs.

The difference was so big, I now have a much more satisfied driving experience. Where I was thinking about selling the car before, I am now in love with my MSP all over again.
 
yeah, my car has been hauling a lot of ass after I replaced the EGR valve with the new canadian one... it still ran bad at low speeds because the plugs were still fouled up from when the EGR was bad, but I cleaned them up and it's all good

Are the Canadian EGR's better? Where can I get one, due for a replacement.

I just got off the phone with Mazda North America and the local Mazda dealership, and they both say there is nothing about any unlimited warranty for the EGR in our cars. There is a technical service bulletin, but it only instructs the technicians on how to diagnose and service the issue.

Looks like we're on our own with this problem. (boom07)

Is there a different part # for the Canadian EGR? Maybe I can bounce a group deal for anyone interested since I'm in Canada...

Low Idle

I purchased an '02 626. (This is my 2nd mazda. My first mazda was a '93 protege)
. Everything was running nice. and now the rpm's are too low.<700 when in Park, when I shift to Drive, it goes below 500 or it stalls.
I read here it's possible it might be the EGR, which I will attempt to clean.

But, I read somewhere else, that it might also be the MAF.

Please advise (HELP!)
