I'll do that and report back.
The funny thing is that I meant to replace all the vacuum lines a year ago when I got the car, as part of establishing a baseline. I just never got around to spending the 1/2 an hour and $8.00 worth of vacuum line.
I did all the fluids, filter, ignition components, and check the brakes....just forgot about the vacuum lines. The engine seems to run much smoother than it did yesterday.
