I have a 94 honda civic 4dr 1.5 sohc w/ a full 2inch exaust system without cat, long ram intake,helix (throttle body spacer), larger wires and 2 step colder plugs. For some reason Im running lean. The a/f says lean, the headers are blue and it smells. I rulled out the o2 sensor and the motor has been taken apart and looked at internally. I have 151 pounds of pressure in each cylinder. The motor runs fine it is just to slow for what i have done to it. I have had a stock honda just like mine run me over and at the track it ran a 18.5. Something is making me drastically slower and i can figure out what it is. The car i immaculate but to slow for it appearance. Some tell me something about how to fix this.
