i got a B16a2 and ive got about 75000 miles on it. My first problem i recently got was my idle being erratic from .8 to 1.5 after I drive a little and come to a stop. I'm guessing IACV needs changing or cleaning, could there be any other reason? Then my car started sputtering (for lack of a bettter term) low end, like it does in v-tec when the oil needs changing. So i changed the oil but it still sputters, but not as much. So i then checked to change my spark plugs. When i did this, cylinder 1-3 had a serious amount of oil! Why is this happening, do i need a new head gasket or what is it? I havent driven my car since, I really need help on this!
