Well you see, here be my issue. I have a 84 grand prix with a 305 4bbl, standerd stuff, but the thing is every time i rev her high or get above 30, she shuts off and lossing power steering and brakes on windy mountin roads is not exactly benuo, almost gave a few people a brand new garage if you know what i mean. But back on topic now, to make matters worse my scan tool wont read the car, the port isnt functioning for some reason, so im kinda completly cluless here, any ideas or theorys would be a great help. Thankyou for your time, sincerely, a broke teenager who cant get laid without his wheels.
