I have a 92 Civic DX HB. And changed my engin, to a 99 Civic CX. Not a big deal, but I am having problems with my idle. The car is rough idleing, at any temp. The rpm's are normal for a few min. then drop to almost 0. When I drive the car, it seems to run normal. But if I try to keep a steady speed the check engine light comes on. (code 43) I have checked my injectors,distributor,plugs,wires,and changed my fuel filter. I also checked my oxygen sensor. The problem is still the same. What could it be?
