i can only say what others have told me:
check vacuum lines.
make sure the gas cap is on tight.

How important is having the gas cap on tight? Before it broke down I or my husband one lost the gas cap. But it was running fine without it. Could that keep it from idleing?

by pup was missing a gas cap when i bought it.
it would idle some, then die.

i did a quick tune-up, (oil+sparkplugs), and new ?ERG? valve and a new gas cap. then, it would idle.

we think we found the problem.
There is a hose on the bottom of the intake that looked like it was on but when my husband reached down to check it it wasn't on at all. Put it on & it idle's, still a little rough but hopefully we can work that out.

Thanks for all of the help

glad to be of help.

try adding the gas cap. that might help out on the rough idle, but i'm not 100% sure.

two other items i've read about were replacing all belts and doing a valve adjustments. i haven't done these, yet. so, i don't have direct experience on how they affect idle. unless i'm thinking of "engine stalls when i hit the gas".

Double check the vacuum lines.
Check the timing, spark plug wire routing from the cap. Rotate the distributor a bit and see if it gets better or worse.
Adjust the valves.
For that year, the fuel cap should not make a difference other than safety. Get a cap, now. Newer cars have a sensor on the cap. If it is not on the engine will not run or check engine light comes on. Good luck
