Answer
Checking for vacuum leaks would be a good step.
I would connect a vacuum guage, and that way, you can see if a valve might be sticking, or not closing.
A compression test could also help.

I will send you a couple links to a great Chevy forum, that is free, and a wealth of help.

Here is the referral from Fixitfox33,...that is the name I use there.

Then go to the 1973-1987 Fullsize Trucks, and browse around, and/or post a new question.

Here is that section.   http://www.chevytalk.org/fusionbb/showforum.php?fid/60/
