hesitiates/stubles when accelerating 700 1989

Bruce:

You could have a throttle body or an idle air control valve that need cleaning. The TB needs to be cleaned off the car because there are some small passages that you can reach better that way. Be very careful removing the throttle cable connector, or it will break. Don't use carb cleaner; get special TB cleaner.

The IAC valve is a bear to reach; it is under the intake manifold, so don't try it with a hot engine. The hoses can be brittle and break, so be gentle. Hope you have thin arms and long fingers.

If the problem persists, maybe it is a clogged cat.
