How To: EGR Removal and Cleaning for Rough Idle Fix

[kyle's protege5]

i think i've said this before but if anyone wants a used one of these with about 5000 miles on it just pm me. pulled it out when i turboed my car. A lot cheaper than the stealership or Napa

 

[theROOSTER]

can this be an issue(and fix) on Automatics as well?

I have a used 2002 MP5 with 124k, and it seems to idle in the 300-400 range, while at stoplights in D.

it's not too rough, but there' s little "gurgle" and shake every now and again, and once in a while it drifts from 300-400 up to 600, and it always feels "smoother" when at 600.

Ive pulled and cleaned the MAF, and just run seafoam through the brake-boost vacuum line. (currently, no change yet but nothing got worse)

I have some new plugs to drop in now (going to try some G-POWER BKR5EGP 7090's) and thought maybe cleaning the EGR may help as well....

thoughts?

im not sure if this has come up here yet, though i'm sure it has and i just could find it..if sorry sorry for repeating..but what are the chances of taking the EGR off without damaging the gasket? I want to to this asap but should i buy a gasket first? thanks!

I'm still using the original gasket after a rebuild / cleaning, no problems.

One part that I would like to point out about the gasket:

Some have metal gaskets and some have fiber. The fiber gaskets suck and will fall apart when you remove them.

From what I have seen MSPs have fiber and MP5 has metal.

great thanks for the info..so am I safe to assume the my protege has a sucky fiber gasket? thanks again

How about the gasket on the MP3? I'm crossing my fingers for metal... (drinks)

The gasket on my '01 Protege is metal - I just looked and the part # is the same for all 99-03 Proteges, P5s, MSPs, and MP3s, so I would assume that all of the gaskets are metal.

Mine is metal and the oem gasket I just received from the dealer is metal. I only bought it because I bought a new EGR and I was worried about dropping it again during the install. It's hard to find it down there.

k thx. I think I might do this tonight when I get off work. I just ordered a new header so I might as well make the egr nice and clean for the install coming up. I'll be sorta pissed if I strip a screw tho (bang)

 

[ucMP3]

Not bad at all... I've got the egr soaking in carb cleaner right now. Took maybe 5 min to get it out of the car and taken apart from the solenoid. The 4 screws (the ones like cheese?) were set in a little bit but I didn't even use any PB blaster. I was anticipating a lot of trouble from hearing everyone else on here, especially since I'm guessing this is the first time its been removed in almost 9 years. But so far, so good! The valve is already moving A LOT more freely now, it was pretty gunked up so hopefully I notice a little bit a difference in how smooth the throttle is. On that note, by the looks of it, getting it put back in will be much more of a pain than taking it out. And I'm not sure I should even mess with the Idle control valve, I don't think I have the proper torx wrench needed anyways it sounds like.

*Edit: Just finished, it idles real nice now... Just took it for a quick test drive and it feels/sounds great. Nice write up!

OH HEY???? Canada has a different EGR valve? Maybe that doesn't suck as bad as our USA version. Does anyone know the difference???

 

[ucMP3]

The specifics are posted in this thread a ways back... But basically it's got some extra stuff that helps it burn off the carbon deposits from the exhaust manifold so it doesn't build up as bad.

 

[LASERBLUE135]

So it doesn't suck as bad as the USA version!!

Precisely. Its supposed to be much improved over the original US version.

Just cleaned my EGR valve.

fixed these problems:
sporadic idle
Dip in RPMs when clutch depressed

And btw, to read the gauge under 1000 rpms;
0 = 0
first heavy black line = 500
each line after that is + 100

so its:
-1000
-900
-800
-700
-600
-500
-0

What is an IAC, and how do you clean it??

Anything else I can clean?

I cleaned my egr valve by soaking it for about 5 minutes and scrubbing it with a tooth brush (though it was hard to get deep in there)
Is that 'good enough' of a clean? or should I have been more through?

baa, lol ima just buy me a new one and put that sucker on. lol, though its sounds easy to clean it, but the hassle isn't worth it for a new one and not have to worry about it for a few years.
