make sure throttle cable has slack in it

make sure the throttle opening is clean

those don't help, turn the idle air bypass screw all the way in, then back out 1.5 turns (just like a carb!)

Also, you'll see two holes inside the TB opening, put a fibger over both of them (like Helms sez to do)

Would a faulty brake booster cause a vacuum leak? You said it starts when you hit the brakes. I'm not too familiar with boosters, just throwing out an idea.

now see i was kinda thinkin that aslo abot the brake booster but hell idk :1

Re: reving up and down. help!
 

I guess the easiest way to find out, would be to unplug the vacuum line to the booster, and plug it temporarily.
