New Manifold Install ??? Cruise control too

[kpack5982]

What product or method could I use to clean off a used upper and lower I got? Seems to be some buildup in there and want to get it out before I install it tomorrow. Also i was looking for a picture that labels all of the lines that go to the intakes so I could get them all marked for the time being, making it a quicker project. Oh yeah, one more thing. I was thinking about the vacuum and the cruise control, does the vacuum have anything to do with the cruise staying set because the car tends to slow down and eventually the cruise goes off, but if I give it some gas, it will rev right back up to where it is set, any ideas?

One more thing... I noticed the hole in the very center of the intake, is that the one meant for internal egr? Will that work without problem with teh stock egr on my 93?

Carb cleaner should clean it out.

So what should I use to rub the carbon off inside the manifold ports? like a lint free cloth from an auto parts store?

Toothbrush works great.

Just call me stupid cause I at least know the answer to hole question, it's the egr, well duh, anyways, any help would still be great for the cruise question

If your manfold has the hole in the lower & upper for the EGR, it will work just like the stock EGR did.

The cruse control servo that hold the throlttle stready uses vacuum to actuate it. A vacuum leak in the servo could cause your problem. However, it is more likely that the speed control amp needs tweaking. There should be a set screw on the amp that adjusts it's characteristics.
