well its not the o2 sensor, so i think im gonna put a spare ect in (engine coolant temperature) sensor here is my reason........a cold motor needs more fuel and a hot motor needs less. This sensor tells the ecu when the engine is hot enough. So I am thinking that the sensor isnt sending the right information to ecu to cut down the fuel, since i only have the miss after the engine is warm and it is running extremely rich (10.9 gallons gas to 170 miles) with a b16 swap tho without every hitting vtec or beating it. If i get on it alot i can get about 10 miles out of 5 dollars of gas $1.94 for premium here
