I have a low speed miss that I couldn't find. Today you could feel it when power breaking but when I disconnected my EGR valve it smoothed right out. So my questions is, does that mean a need for a new EGR valve or could there be a problem with my programing that could be causing it. I don't want to go part swapping unless I have to.

Second, does anyone know the part number for the EGR valve on a 95 SSEi? I have looked on Ebay and could save some money there but I want to make sure I get the right one.

Any help would be greatly appreciated.

Ahh your EGR is probably leaking. Might try yanking it, cleaning it, and putting a new gasket under it to see if that helps.

www.gmpartsdirect.com - their catalog should have the part #

my experience with them says replace it, but cleaning is a cheap way to start! My grandma'* pontiac 6000 had a similar problem and the egr had to be replace...the plunger got to sticking.

JDB: what year was that 6000? Because I betcha that was a mechanical EGR valve.. found on the midish 80s cars.. which had a vacuum line, which [dr jay said, not me] is controlled by the ECU.. ECU controlled vacuum.. who the hell thought of that???

I said what?

My bad. It was mechanical. i will now close my big mouth

Anyway, yours is electronic. Ofcourse you should try to clean it first. Why spenf 80 bucks when a 2.00 dollar shot of carb cleaner would fix it? Try the cleaner, bolt it back on. If the miss is still there then replace it. I average about a 50/50 success ratio.
If it doesn't work your only down by one hour of time. If it does work your up $80
bucks.

Try it. If it pukes by another. I say ALWAYS try the cheap stuff first.

I had the same problem, it finally started throwing codes. My EGR was able to be cleaned and that fixed the sticking open problem.

9 time out of 10, cleaning will buy you at least another year. I've owned my SSEi for 2.5 years, and I've cleaned it twice for sticking. Still running strong.

Ok, I appreciate the help and I am going to clean it and put on a new gasket. I looked in the Techinfo for instructions but couldn't find any.

Can anyone share the cleaning process.
