How To: EGR Removal and Cleaning for Rough Idle Fix

[90210brandon]

At 72,650KM encountered rough idle that period under this bulletin announced that for EGR's in the covered years, the warranty has been extended to 2008.

This may not be the 100% exact nature of things, but only what I understand. Regardless, this was the result: Mine was replaced for free.

Good to know. Thanks Lance!

when my valve wouldn't move, i think i left mine to soak in diesel for 3-4 days. after which i still had to play with it like crazy and use more SuperClean.

....






and then a couple months later it got stuck again, i cleaned it again and it seems fine now.

Thanks for the How To. I somehow got to 90K before the car started to stall out on me. I decided to just replace the EGR completely. ~$125 and an hour of work. It's like getting a new car.

thats what i did after following the directions here only fixed mine for 1000 miles then it crapped out again. so i replaced it myself.

The EGR valves are starting to get REPLACED more often on the boards. Can someone post the P/N's for the:

MSP EGR
P5 EGR (if diff # than MSP)
MSP IAC (if this get replaced also)
P5 IAC (if diff # than MSP).

the part # for the new redesigned egr valve for any protege model is: FSY1-20-300-9U
to be honest you should replace the gasket also but mine was in good sahpe when i took it off so its your choice. gasket was cheap anyway. look at reply #263 in this thread for pics and some other info.

 

[P-Funk!]

Yeah, that appears to be the concensus. I plan to swap mine if it starts to stumble again...

Just a few questions:

1. How do you reset the PCM, as is mentioned in several posts.
2. Replacing the gasket is not often mentioned, but is mandated in the TSB located here: http://www.msprotege.com/forum/showthread.php?t=123654270
3. I bought my car with about 65K miles, and now am approaching 116K with this problem. Are there other things to look at with so many miles?

Thanks

I also did the sea foam treatment at the same time, it really smoothed out a lot of things.

my car died today at idle

yay =(

 

[00protegeracer]

is this the same for the 1.6 engine?

 

[RABID_MP5]

My EGR was (and is still) stuck open with carbon - awful idle etc. I just disconnected the exhaust tube at the union, a few inches from the header/manifold, inserted a dime and reassembled. Runs great now with the exhaust supply tube blocked. Any drawbacks to this simple method? It sure idles and runs great. Just my ten cents worth.

 

[SoonP5ismine]

the only thing i think may happen is worse than normal emisions.

 

[FL_PR5]

the only thing i can see as "fatal" is the dime somehow finding its way, or a piece of it, into the engine. just my .10 cents

 

[NCZ13]

youll get a CEL for insuffeciant EGR flow i bet.

I just want to say that you people ROCK!!!!
A few months ago I brought my '01 Protege in to get checked out as it was idling rough and the check engine light came on. They gave me an estimate of over 600 bucks because they said the code is showing a bad o2 sensor. Well, I've been putting it off over the holidays and was going to bite the bullet when I found this site/post. I said, "what the heck" and gave it a try today (outside -5 degrees celcius).

I just put it all back together and it's purring like a kitten. Went for a test ride and it's working beautifully. I can't thank you enough. I must say too, when I had the valve apart and when I pressed on the spring it was sticking badly. So I knew that would be causing at least some of the problem.

Again, thank you from the bottom of my wallet.

damn, 600 bucks for a simple 2 bolt bolt-on solution. youre welcome!

i agree that 600 bucks is a bitt steep but its not exactly simple to replace it. you cant get a regular open end wrench in there to get a good grip on the bolts. its not as easy as it seems but its doable.

The 600 was for a tune up as they couldn't exactly diagnose the problem, this also included a new factory O2 sensor as the code reader was telling them it needed to be replaced. They didn't even mention the possibility of the EGR valve. That would have probably been another 2 or 3 hundred. After doing this clean-up on the EGR it's all like new (the check engine light even went out).

i hate to tell you but you probably will have the same prolem return in a month or 2. they have a new redesigned egr valve now that suposed to be better then the stock ones.
