I turned on the car this morning and it idled over 1000 rpm which is normal cause it was cold. In a minute in went to 900rpm still normal, but then went to 600rpm quick. Soon after it went to 500 then started bouncing between 500-300 rpm. Finally the car shut off itself.

I restarted it and the car idled at 500-300 then shut off again. The car was running ok the night before and i havent been hard on it for a while. I think the problem is my intake manifold gasket or hoses, but im not sure. :1zhelp:

my cars a NA 91

Did anyone have this same problem or have any ideas of what the problem might be? Thanks for viewing
