so here is a little update. I unplugged and reseated just about everything I could get to: switch on steering wheel, ASCD module under dash, vacuum pump in engine bay.

I went on the hwy for a test and still the same. This time I kept my foot on the gas as I was setting the cruise so that I can feel if it goes down as usual. Well, it didn't. The green cruise light came on and the speed started dropping as if nothing was on. I kept my foot to see if the pedal will go down when the car down shifted. It did down shift but that was not triggered from the TB or cruise cable pulling, it was an electronic shift I guess.

So now I am thinking that it's either the vacuum pump or the actuator. I pulled the actuator off the car but am not sure how to test. I don't have the FSM where I am at right now so no idea if it says something there.

How do I take the vacuum pump off? I can't seem to figure that out
