    first parts sounds like leaky vacuum or bad fluid. second part sounds like timing way off (stripped cam gears?) or corroded distributor rotor


    also- why'd you wait almost two years after registering to make your first post!??!

    not sure about the enigne dying but the tranny needs to be rebuilt or replaced. I had the same problem and some grinding noises coming from the rear of the sub and i thouhgt it was the rear end. had the tranny replaced and the grinding noise went away.

    On the 700, it isn't going to be vacum... they don't use it. Check your TV cable adjustment (not sure where I saw it... but somebody has a real good write up on how to do it). Also, it could be a governor... but when my 700 had these symptoms it did require a rebuild /forums/images/graemlins/frown.gif. The engine not starting like that could be an ignition module... had that happen once too!
