The link explains how to test for vacuum leaks.

The air hose is the one between the air cleaner and throttle body. Check for cracks on the hose or its connection.

Vaccum leakages can cause high idling and misfirings and you should try to get this rectified first. Forget about what people telling what it could be and to check this and that. You need to follow proper procedures for diagnosing problems and not guessing on prossibilities. I only work on information you provide so if I get the wrong data, you are going to get the wrong answer.

Get a can of carb cleaner and after starting engine, spray a little the carb cleaner around suspected vacuum leakages and if the engine idling changes, that is the area you should be looking for leaks.

Do not over spray and concentrate on one small area at a time, with short spurts.

Injectors are at intake manifolds, attacheed to the fuel rails and not directly visible.

Ok.I appreciate that response.I'm tired of guessing& being mislead! This is my new issue! I changed my last spark plug! Now the car cranks w/ease but will not stay on! It's like one thing after another! Back to back! If I crank& keep my foot on the gas. Everything is fine. Car is idling right. All the good stuff. When I take my foot off it shuts down! That started after changing spark plug!

Recheck your work. Something could have not been plugged in correctly or loose.
Get a scan done to check for trouble codes. Most parts stores provides free scanning servies. DO NOT change anything first, just let us know the trouble code is fany found.

I don't go around guessing, we need to diagnose the problem and remember, you are our eyes so what you give us is what we are working on.

Yes! I appreciate that! The not guessing part! That's what I'm tired of doing.(Guessing) I have to try to get it some where ASAP to see why it won't stay going! Every one is giving so many different answers that I'm lost.I will continue to keep you informed& ask you questions I am totally lost& frustrated right now I don't know where to turn or what to do. I appreciate your time& effort greatly

We are here to back you up so if you have any questions, don't hesitate to ask.

I have this to suggest, forget everything that had occurred and we start from new. Sometimes problems are resolved and a new one comes up due to something else and we tend to overlook those that we have worked through.

We restart from zero and the basics.

1. List out the symptoms presently showing.
2. Check for trouble codes.
