So i have a 96 civic and ive changed the fuel filter and have checked the battery and altenator but it seems like i have to prime the car and then tap the gas once it starts to keep it running i have 5 codes (i havent reset them to see if they popped again)(and ones for an 02 sensor ran fine and had that code before the other 4 are new) its saying i have a cylinder 2 and 4 misfire but it runs fine im listening and havent heard it misfire i also have the codes c0848 and c2b10 and c0313 i dont have alot of money but i have the tools and can fix it myself so id like to find out what the problem is so i can buy the correct part and replace it
