I have a 05 civic coupe. I recently noticed that when I was at a dead stop and tried to excellerate that the car hesitates and sometimes theres a pop! sound. However it only does that when I'm at a DEAD STOP. Once the car gets rolling, there's no problems switching into different gears or anything. It seemed to me that its either a exhaust or a fuel injector issue. I took my car to the dealership and they said I need a new transmission. I dont know about that. If anyone has any suggestions as to what this may be please let me know.
