Did this start out of the blue or after something was worked on under the hood?

It's usually a good idea to check your spark plugs after doing it, because it can actually foul out your spark plugs since it works "that good". But again it really depends on how and how much you run it thru the car. |

I don't think it's any type of "fouling" issue.......unless it's fouled spark plugs possibly. These engines are always filthy inside since they re circulate crankcase vapor back into the intake, but apparently it doesn't bother them at all. Really sounds like a vacuum leak to me is the most likely cause. Incidentally, what kind of plugs are you running in it? I have found that they really don't seem to like Bosch Platinums for what it's worth.

Update on idle issues.
I completed a base idle reset again and it seemed to be idling ok. When I turn the heat the idle lowers and nearly turns off. I will see how she runs in the a.m.. My car has motorcraft spark plugs, but it need to probably change them soon for a tune up. There is also a pretty bad exhaust leak on the passenger side I will address as soon as possible. I wish she was ready for the 50th Anniversary Mustang car show in Charlotte, but she is not ready. Maybe I will be able to show my car at the 51st Anniversary next year. Thanks for all of the help.
