Customer Question

Hi I have a 1990 Saab turbo with a slight vacuum leak. I'd like to drive it tomorrow to my mechanic 100 miles away is that safe? It's hissing very slightly and only rough idles below 1.5 rpm. Thanks!

The computer will sense the lean condition and can compensate for it by increasing the pulse width to the injectors. If it is just a slight leak, there will be no problems driving it to your mechanic.

When I open the hood, the hissing isn't slight. I just yesterday had the alternator replaced. I may want to drive to the place that did it nearby in the morning-would they be able to fix it within an hour or so? I maintain this car very well and I don't want to blow a gasket.

I am sorry for the delay. The shop that replaced the alternator should be able to fix the vacuum leak. It is most likely a ruptured or disconnected vacuum hose.
