CNBZ34 Posted January 9, 2007 Report Share Posted January 9, 2007 So, here we go again! Last post, uneven idle and intermitten miss. Discover that the EGR valve was failing. Replace valve and car runs great again. Less than a week later, MIL returns, uneven idle returns and so does code 32. WTF??? The new valve appears to have had moisture coming out of it on the bottom of 2 of the solenoids on the bottom of the valve just above the base. I checked to make sure the passage was clear but kinda difficult with the plenum on the car. Any suggestions? i wonder if the new valve failed. When i removed the old one, there was some accumulated moisture in the passage way.... I'm starting to dislike my car again. Quote Link to comment Share on other sites More sharing options...
Brian P Posted January 9, 2007 Report Share Posted January 9, 2007 probably a partially clogged passageway. Very common issue with that intake manifold. ultimately you may have to take the manifold off the engine in order to clear it out. I've seen them get cleared out with a stiff wire, even a coat hanger, after spraying the passage heavily with brake cleaner. My friend's old twin cam engine had a chunk of carbon stuck in there after several cleanings. Last time he did it, he finally got it out (didnt know it was there) and the code never reappeared.

slick Posted January 9, 2007 Report Share Posted January 9, 2007 Yep, just as Brian said, you need to clean the passageway. I guarantee that you didn't need to replace the EGR in the first place. I've had good luck with throttle body or carb cleaner and a coat hanger. Spray it it, then go to town with the coat hanger scraping the metal.

CNBZ34 Posted January 9, 2007 Author Report Share Posted January 9, 2007 So the signs of moisture exiting the bottom of the 2 solenoids at the base of the valve is a sure sign that the passage way is clogged huh? That was $200 down the drain. I tried using a piece of steel wire in there but I could not seem to get it all the way thru. Does the passage way go in then up or straight in or in then down? not sure. I really don't feel like pulling the plenum off. My luck there aint no gaskets in stock anywhere either. A new car and payments is starting to sound pretty good about now. Just disgusted. With the tons of $$ that's been dumped into it and it is basically a new car.... crate motor, trans, rack and intermediate shaft and tie rods, struts, most sensors, plugs/wires, alternator, brakes, wheels/tires, exhaust, bla bla bla bla....I don't have time to dick around with it anymore.

slick Posted January 9, 2007 Report Share Posted January 9, 2007 It's pretty easy to do. Unbolt the egr, spray tons of cleaner, let it sit for a few minutes, then take wire or a coat hanger and push in and scrape away. Wipe as much cleaner and carbon off as possible, reassemble, reset the ecu to clear the code, then start back up. It'll probably run rough for a minute or two with the cleaner in there, but it should even out after a little while. Quote Link to comment Share on other sites More sharing options...
CNBZ34 Posted January 9, 2007 Author Report Share Posted January 9, 2007 going to do it this evening when I get home from work. Here's another idea after doing some searches. I discovered that my stalling problem fits into the "phantom stalling" catagory from all that I've read. The fix was to upgrade to new injectors. I found that Schmucks online has a good deal on a set of 6 ACCEL injectors but have them for 24 lb flow and 30 lb flow. Any idea which ones I might have and what might happen if I just went with the 30's? Quote Link to comment Share on other sites More sharing options...
skiiirt Posted January 10, 2007 Report Share Posted January 10, 2007 The best fix I have found is to rebuild the EGR Valve itself and remove all the gunky carbon crap from inside. Make sure to replace all the gaskets when removing the valve. Quote Link to comment Share on other sites More sharing options...
