EGR valve? Check vac and electrical connections. :smoke:

vacuum lines had moisture in them, blew it out cel goes out for a while then comes back on. electrical connections are allright.

Not real familiar with specifics of these EGR systems, but let's start with the basics.

Code 332. Can I assume this is a memory code? Can I also assume that, because you didn't post any other codes, that it passed the KOEO test? Did you perform the KOER test? If it passed the KOEO test, and you haven't yet performed the KOER test, then I would start by performing the KOER test. It is often easier to diagnose things from the KOER test than from memory. If a lot of this is Greek to you, then review the instructions for pulling codes so that it does make sense (see tests at www.dalidesign.com/hbook/eectest.html if your scanner doesn't have good instructions).

Most likely needs a DPFE... check the Key On Engine Off voltage, it should be around 0.6v. If it's too far off that, it needs to be replaced.

only code that came up is the 332, did KOEO and KOER. The two lines that have moisture in them are the ones that come off the exhaust manifold. I guess they are not vacuum lines. With lines diaconnected i can feel the exhaust comming out. Like i said when i blow the moisture out the CEL stays off till i shut it off, then it comes back on after a while, maybe I'll try the DPFE. Thanks.
