Code 43
I have a D16Z6 with a P28 ECU in my 89 Civic DX. I have a AEM Fuel Rail, Lightened stock Flywheel, and a 4-2-1 header (Cheap no name but it seems to work) I have one code 43 Fuel system problem. The car seems to run strong the Cam kicks in and everything but this code comes on it takes from 5 min to sometimes an hour before the light comes on. Fuel Pump? also the header has the O2 sensor on a Single primary tube. Any ideas?
