This is my first post in this section, im checking on something for a friend. Not exactly sure what year but he has a civic coupe with a sohc vtec motot that he says bogs from time to time at about 4200 rpms. He said that it doesnt matter on any kind of weather conditions, wet,dry. He also said that he has to completely let off then get back on it. I have a cold air intake on my car and when it rains my boggs at about the same rpm but I can always peadl through it. Its more like a cold water intake sometimes.
