I have a single cam OBD-I vtec engine currently at around 13:1 C/R. My injectors, fuel pump,fpr,etc is stock. I only have enough bones to spare for bigger injectors OR V-AFC for now. Which would be better for me as of now until i can afford the other one. If i need injectors, I would like my idle not to be too eratic . I have had 310cc before in my 99ex and it threw all kinds of codes. Even with a fuel controller, I still cant bring those ponies down to a good idle. Any help will be appreciated !
