and I don't reply to stupid PMs... not a problem for me
my mods have nothing to do with how my sig is nor have nothing to do with the issue... I'm not ashamed of what I have if that's what you're trying to make me look like
I just hate people who have a sig that fills up an entire page.. huge pic of their car with some hot girl, some random "funny" pic, all their mods line by line instead of all on 1 line, etc

I'm in the process of doing that right now. It's pretty straight forward.
1) Remove the rubber hose
2) Umplug the connector
3) Here's the hard part if you don't have the correct tool. Remove the 4 screws. Screwdriver won't work, you'll just strip the screws. See my post above about what to do about that.
I'm gonna go out and finish the rest right now. Oh, Autozone wants $499 for that part!!! I got mine from partsgeek.com for about $184.

Update:
Cleaned my stepson's EGR about 6 months ago (thread #806). About couple of weeks ago, he came home with the car having hard time starting and rough idling. I didn't think it was the EGR since hard starting was not involved. Autozone code reader said:
1st time:
Idle control system RPM lower than expected
Probable cause:
Large vacuum leak
Blocked Air intake or exhaust system
Throttle body damage
Engine Mechanical contition
2nd time:
Random cylinder misfire detected
Probable cause:
Lean Air/Fuel ratio
Weak ignition system
Engine mechanical condition
Vacuum leak affecting one cylinder
So we replaced the Idle Control Valve which didn't fix it. As a last resort, we decided to take a look at the EGR again...Guess what? The damn valve was basically stuck!! We soaked it over night, it still won't move freely so I took Dremel with the cup-wire attachment and clean it out until it moves freely. Reinstalled it, prayed, and start her up.......and she started right up, the rough idling is gone, the CEL is gone. Now she's running smooth as before. Don't know how long it's gonna last this time.

Hope you have something similar to this

Makes the job much easier
I had a similiar experience, but it took about 1.5 hours for me. The screws being made of cheese is funny as hell! I did not have camel ass tight bolts holding on the EGR valve. Mine were torqued at the factory to "payback for Hiroshima". http://www.sears.com/sr/javasr/product.do?BV_UseBVCookie=Yes&vertical=TOOL&pid=00944815000
LMFAO!!!!!! XD XD XD (shocked)(shocked)

ya, the screws are the same youd find on any carburator, complete s***! I had to put all my weight into it to get them off with a regular screwdriver. next time I will take them out and have them replaced.

The EGR valve looks completely different for the early 90's models, so it seems reasonable that the gasket would be different too.

dirty EG valve
Thank you so much for the info on code PO 401 and dirty EG valve. You saved me time and money! The description and pictures helped so much in the repair.

im proud to announce that the new redesigned egr valve that i installed at 50000 miles is lasting longer than the original so far. I am at 101000 miles now.
I agree, it's a sig, not a 'look at me' section.
