I was driving along on the interstate at 70 mph when I heard and felt a loud bang from the engine compartment. It happend twice about 4 or 5 seconds apart. a puff of black smoke came out of the exhuast right after each bang. I tried to give it gas but it didn't respond so I just pulled over. I tried to start her up but it just cranks. NO start. It's getting gas and spark. i don't know about compression.
Anyone have any ideas????
