erratic idle?? 68 LTD

[Thomas C Potter]

Yea, me again. Been running good, has developed an erratic idle tho. I'm thinking vacuum leak. Thoughts??

It would have to be a fairly large one so look at the pcv hose and the one to the power brake. Also a possibility is dirt got into the idle system you can try taking out the idle screws and blowing in air then rest the idle mixture. If that fixes it or changes it that would be signs of dirt in the carb. Or ?? water in the gas

This ^^^^ before you mess with anything! They'll tell you if its something as simple as an imbalanced carb mixture setting.
