89 5.0 mustang
My mustang was running horible. On inspection I
found a vacuum leak. Fixed it and now she runs
perfectly for a minute then starts to sputter and
die. Any suggestions of what to look for? A
If 1 vacuum line was bad there is a chance there is more than one that is bad. What you can do is spray brake cleaner on all the lines you can see (take care not to spray exhaust manifold or distributor cap as the spark may cause a fire) and when it starts to run good that's the area you should be looking at.
