i just noticed the other day that my car sounds like it has an exhuast leak. i havent had time to really check it out but i can hear it. anyways i noticed as well when i get up around vtec my car seems to sort of bog then get a burst like something is holding it back then it goes back to normal after about 6k rpms. i dont know if the exhuast leak has anything to do with it or not. i can almost hear a pop when it starts to hesistate then go back to normal . i got a day off so im gonna go check out the leak today but i was wondering if there would be anything else that would cause my car to do that. its not throwin a cel or anything either. also for the record my car is obdI. thanks guys
