Hell All,
I have a 1993 Chevy Caprice Classic with a 5.7 350 ci motor Fule injected. On Saturday, I was driving vehicle and it drove perfectly, however, when I stopped and spoke to a friend for 10 min (Vehicle was idling for about 10 min), it suddenly died. I restarted vehicle and it ran really ragged. It would idle up and down (RPM from almost zero to 1000). I just kepts idling up and down. the check engine light did turn on while I was moving vehicle to a safer place. In addition, there is an audible hissing sounds coming from under the air cleaner. It sounds like a vacuum leak for sure. I am not a mechanic, and hope to take the thing in soon, but I would like some ideas so I could maybe look and see if it is something obvious and easy to replace. Thanks in advance for any imput,
Kevin Gowen
