Hey. When i was driving my 91 si hatch (DOHC ZC swap) the other day, i raced a civic si coupe with a d16z6, and beat him. then a bit down the road my car all of a sudden starts diying out. complete loss of power, car starts bogging out when i give it gas. the car starts rumbling. pull over check it out and it idles good, rev it a little, no problem. then start going again starts doing it again. the motor hasn't givin me any problems yet. i did the swap myself about 4-5 months ago. i didnt drive the car the day after that. today when i was on the highway about a 25 minute drive it did it once but barely. i parked it, and went to class and when i drove it after class no problems. anyone have any ideas??
