How many times are we going to have to answer this question, Tina? I know
you've asked it at least three times. I gave you a pretty lengthy
explanation a couple weeks ago, and now you're asking all over again.
You almost certainly have a vacuum leak. If it's not that, then you may
have a very worn timing set. The place to start is by checking all the
vacuum system. In fact, since it's so old, I'd just replace every vacuum
hose, and check the gaskets in the intake while you're at it.
With the limited description you're giving, that's about the best guess
anyone's going to be able to give. By the way, if you're anywhere near the
Washington DC metro area, I'd be glad to take a look at your truck, free of
charge, to point you in the right direction.
