As to the vacuum lines, I personally recommend a two-fold approach. First, I prefer a detailed and thorough visual and physical review of all the vacuum lines.

Go ahead and start at the throttle body and feel and view each vacuum line, following them all the way to their terminal ends. That includes under the airbox and to the evap/charcoal cannister. Review each vaccum line in turn this same way. The common places for cracks and splits is at the rubber connectors. If you have any suspect connectors, I suggest replacing them all. It'* low cost and get'* the job done once and for all. All of the straight connectors can be replaced with a simple cut piece of rubber vacuum line purchased at your local parts store.

Even a small split or crack can cause more grief than would seem possible.

Second approach that many use is to spray some intake cleaner around all lines while the car is running and listen for any engine sound change. IMO, this is a secondary check and should not be substituted for the actual on-hands check mentioned above.

Thanks Boosty. My current wires are AC Delco. I haven't changed them or plugs, and I have had the car 6 years and 75,000 miles. They must be ready for a change

I have a Checker auto les than a half mile away. Thanks for the tip

Thanks lash...That helps... How many vacuum lines can there be? Are they soft flexible lines? (I feel like a simpleton asking this)

Any pictures maybe? I think I did read a thread about a connector that cracked, and the guy thought he did something bad.

I will check them this weekend

Thanks all.... this is great stuff

Your vacuum lines are typically a hard plastic small diameter line using rubber connectors. They run from the throttle body to the brake booster and the evap./charcoal cannister under your airbox. Here'* an old pic where the needle-nosed pliers are pointing at a rubber vacuum connector that has a crack in it. That hard plastic line running to the right is a vacuum line.

Check all the lines and more specifically the rubber connectors. This includes any elbow-shaped and "T"-shaped rubber connectors.
