Car has always thrown EGR codes, but I'm down to JUST 32. I have Rodney's stainless steel lines, a brand new EGR valve and EGR tube, no vacuum leaks (idle is perfect, can't find anything with starter fluid anywhere). I pulled the EGR solenoid today, took it apart. It looked to be in pretty good shape. There was some corrosion around the pressure switch (square module that connects to the side - how does this work? Searched like crazy and couldn't find info on it), but the coil was surprisingly clean.

I have all the "right" readings for OHMs on the ports and at the coil. Put it back in, and 5-10 mins after getting to speed on the freeway, CEL comes on. What am I missing? You can't buy a replacement anymore. Thinking about running to the junkyard and scavenging a few to see if I can fix this. =(

They can actually be had, see //www.fiero.nl/forum/Forum2/HTML/142489.html

I don't know the magic of how they work, but when mine did that I just bit the bullet and replaced it. No codes since.

My code 32 was caused by an elbow connector at the EGR Valve. It looked perfect, but the fit was not quite snug. Those things dry out over the years, and this system is sensitive.

He has one, but holy CRAP $300. I think I'll just try my hand at rebuilding another from a junk yard at that price. Ouch.

I had to replace the o-rings inside of the solenoid to rid mine of the 32 code. Replaced the rubber rings with silicone o-rings to help prevent future issues.
