My 84 se has thrown me a bug I cant find. On occasion it will miss at idle like I have a stuck side seal, then sometimes it wont. I did a compression test today and they were all right around 90, which isnt bad considering its got 217,000 miles on it. Is it a vacuum leak or fuel problem, the ign is sound. Im going to try the power foam thing see if that helps. any ideas would be appreciated!
