Code 332 help

[JonVH]

I recently got code 533 and a couple of others that poped up when my O2 sensor went. So I ignored the others & focused on 332. Checked the EGR sensor (replaced 3 monthes ago) & found the vaccuum lines were broken. Great easy fix, right.
Wrong I still get the 332 code after 10 min of running but now the other codes are gone. I tryed SDPatt's suggestion of blowing into the port right behind the EGR & seem to have no problems with blockage. I also blew into the 2 lines that connect to the EGR & Sensor. Again no problems. What else should I check for?

Related has anyone pulled that plug behind the EGR on the manifold & had the threads partially strip off? Mine did what's a good fix?

Sorry ignore the 533 in the first line.
Should read 332.

Depending on your time and mechanical ability, I'd go for the nostrils inside the intake manifold (most likely) and/or the egr pressure sensor bolted onto the back of your intake manifold. I believe the sensor runs like $60 and takes 10 minutes to replace yourself and requires 0 mechanical ability to do. The nostrils cost me $150 to have cleaned as I am lacking in mechanical ability and have no place to tear the intake manifold off at, but if you can do it yourself, it's free. Having someone else do it can be a trick as most people will have no idea what you are needing... might wanna bring in the description from shotimes.com.

3) Can't help on the stripped bolts, sorry.

If you have confirmed that the flow path from the EGR port to the nostrils is clear, then the problem generating the 332 code is either the EGR valve not opening or the EGR pressure sensor not detecting the pressure change when it does open. Since the EGR valve itself is not very old and you checked the vacuum lines to it, that points to the EGR pressure sensor as the possible source of the EEC code.

Are you saying that you stripped the 8mm Allen plug onthe driver side rear of the intake? Since this plug only resists a pressure difference between manifold vacuum and the slight vacuum when the EGR valve is open, either teflon tape on the threads or a good epoxy or RTV seal should be sufficient. I don't even want to know how you stripped the threads, but remember that the manifold is aluminum.

Thanks for the advice guys.
Sorry I missed the 4/5 EGR posting (just printed it out) but I did reference another thread on the same topic. Is it possible to clear the nostrils with say brake cleaner sprayed through the 8mm allen plug vs pulling the intake apart?

sdpatt- Yes, the 8mm allen plug stripped. Don't ask me how. It never really broke loose and never really freed up until the end. I just figured it was due to heat and not being touched since day one. Two of the threads from the intake are acctually now part of the plug. eek! Would it be safe to try & retap the threads?
Thanks for the insight on a fix.
