I don't think a little but of cleaner will kill the EGR. As long as the plunger returns and seats when you push it it is prob OK. But if you really flooded the EGR with cleaner I guess it's possible to have damaged it. You could try to replace it but these are pretty $$ for a guess.

The vac line under the battery is part of the 4x4 shift mechanism. The actuator is under the battery and operates a cable that goes to the xfer case.

One thing you should do is put a vacuum gage on it and see what vac is. A convenient point to check is at the little black ball on the drivers side of the hood. That is the vac reservoir and the line on the back comes off easily and you can plug that line into your gage. My vac runs about 18 1/2" and is steady at idle (in park, no a/c, no brakes)

If vac looks OK you might then start looking at CPI. Here is one good supplier of new and reman CPIs. Really good cust service. But there are many places that sell these things and prices seem to vary widely.
