It is possible that yes, a undone or missing or hole in a vacuum line could cause this, most cases it would run real bad and miss, or in some cases run and rmps will shoot way up. If you can please give me some more details of what car is doing, symptoms. As many details you can and what you have done or checked so far, then I can trouble shoot a little more to get to the root of the problem. Thanks Mike
Anything is possible,I suppose, but my experience with vacuum lines (cracked, broken, or disconnected) is that performance is degraded, the engine might run rough, have a miss, etc. A simple manifold vacuum test would tell you a lot about the condition of your vacuum system. You need to provide more info in order to resolve your problem. Is the check engine light on. Does the engine turn off only when it's cold? When it's hot? Does the car restart easily and immediately? Does it turn off only at idle, or does it turn off at highway speed? Sorry that I can't be more precise, but more info would help. Thanks, Dano
my car randomly just shuts off, car can be hot, cold, idling, speeding, it doesn't matter, everything including power, (steering, headlights, etc....) turns off, it usually starts right back up, sometimes it happens all day, sometimes not at all, I don't see any patterns, but it runs really rough & you can tell it's missingmy car randomly just shuts off, car can be hot, cold, idling, speeding, it doesn't matter, everything including power, (steering, headlights, etc....) turns off, it usually starts right back up, sometimes it happens all day, sometimes not at all, I don't see any patterns, but it runs really rough & you can tell it's missing
Hey Brooke, can I describe the sympton as the vehicle shuts off and the headlights will go off and then come back on? I'm thinking that the problem is in the battery and its cable connections. The headlights are apart from the ignition circuit suggesting that there is an intermittant connection in the 12 volt feed from the battery. This would include the negative connection. Do not rule out the battery itself! I have seen a battery that was physically broken at the post. Flexing the battery terminal would make or break the connection. If you lose the 12 volt feed, even for a moment, it is the same as if you had turned the key off and then back on. The headlights stay off for the duration of the failure and come back on when the parts touch again. Since the engine was shut off, you must restart it. The rough running and the miss can be and often are caused by cracked or missing vacumm lines. Although it is possible that the computer memory is being cleared at the same time and has to relearn itsdriving parameters. I would turn the headlights on and wiggle, tug, and tap around the battery and cables. If you can make the headlights blink, you have found the problem. Hope this helps!

The answer is yes that a vacuum line could possibly cause you car to die while driving. There are a lot of things that could cause your car to shut down. The best way to handle this may be to have your car scanned by a local shop or possibly stop by your local parts store to see if they will scan it for you at no cost, but first you need to find out what system is at fault. Thanks Rodney
Hello! Speculation does not solve problems...We need to begin an elimination process to solve the problem...I'll rank causes and then we'll, via testing, remove one at a time...#1...it appears that more than one thing is wrong...#2...Since everything dies a complete loss of power is the most likely culprit...#3...rough running and missing may be due to another cause...Stick with me and we'll fix the faults... I sent the procedure to pull a trouble code...That needs to be done...Please follow the given method to check codes on an OBD1 car...
A digital mulit meter works best for the following; Set the meter to read less than 1 volt...Place the (+) probe on the (+) battery post and the (-) probe on the Black/Red wire on the Ignition coil...Start the engine...Turn on headlights and blower motor (need to place a load on the battery)...Meter must read less than .04 volts...If it reads higher send a comment with the reading...
That's two very important tests...The check engine light blinking (codes) and the drop test to the ignition coil...Stop there and send results...Guru...Saailer

Could possible but i do not think so your fuel pump / brain box {computer} may be going bad , are you able to start the car after a couple min.? that gives the computer time to cool down . how ofter is this happening ? Please Let Me Know

YEP VACUUM LINE, STUCK OPEN PCV VALVE AND EGR VALVE, BAD FUEL INJECTOR WILL CAUSE ENGINE TO SHUT OFF.

I would say it is very possible on a 23 year old car. the lines are most likely dry rotted or cracked
In short yea, depending on where that vacuum line came lose or developed a leak.
