Richard,

Your EGR valve is plugged and will act up again. I was able to easily
remove my son's EGR on his '96 SL1 (remove the air cleaner intake, remove an
electrical connector, and two bolts) and see the incredible amount of
coke/soot that had developed over the years.

The part is easily cleanable. I used a long thing flat blade screwdriver to
chip it off the sides of the valve body. I then used a small wire brush and
dremmel tool to clean it and polish the sides once they were clean. After
it was cleaned out, the valve no longer stuck when moved manually.

That was a year ago. Total cost of the fix was about $3 for the new EGR
gasket.

YMMV. Good luck!

Bob

PS Worst case you can buy the part and put it in yourself if you have a
metric socket set. It should take about 15-30 minutes tops.
