Default Vacum Line

Hey guys. I got my 1994 Bonnevile check today and the mechanic said that the vacuum line needed replacement. I didn't trust hiim to much because he said it will be $89.99 to fix it. After I said I don't want to do it he changed his price to $60. I don't trust him so I left.

My car is stopping sometimes and hesitates also. The check engine light comes on sometimes and then it turns off after I restart it. Could it be the vacuum line that needs changing? If so what do I need to do? Thanks guys.

Well I dont know about any main vacuum lines but I have replaced a few of my smaller vacuum hoses because they were deteriorated and one of them was completely torn in half and not even connected. I went to Advance Auto Parts and bought some vacuum hose that they have in different sizes and can be cut into any lenght you need. Im sure other auto parts stores will have some as well.

Get your car scanned so you can find out what those codes are. That'* your first step to finding out what is going on.

Default Vacuum hose

Is it possible that a deteriorated vacuum hose can make your car hesitate and stop?
Did you change it yourself?

A bad vacuum line can cause the engine to act up. But you definitely need a scan to know the exact problem. There'* lots of vacuum lines under the hood.

Where is upper Marlboro? Mass? Anyone live near him? I agree. Scan first, then narrow it down. We have several members with scantools. One maybe near you.

Replacing them is pretty easy if you can get to both ends of where they connect but like others have stated, I would check for codes and then go from there. Autozone maybe?

When I went to get my car scanned, the told me to change my vacuum line. The guy didn't want to give me the code unless I pay $35.Which one is the vacuum line?

I will go to autozone much later.

Upper Marlboro is in Maryland.

I just called autozone and they said that the can only scan cars from '96 and up.
Is there any other places I can go to?

You have the dreaded hybrid ECM, which is OBDI, with an OBDII connector. This is very difficult to find a scanner to do this. I think there are a few members that have sucessfully done this, hopefully they will chime in with how they got their car scanned.
