Does anyone know why my 1989 Civic Dx Hatchback with the 1.5l (5 speed manual) bogs down and almost stalls at low rpms when I give it gas??? I replaced the O2 sensor, and that did nothing. I just replaced the plug wires about a month ago and that solved the problem for a little while. But now it's doing it again?? I also replaced the fuel filter and checked the air filter. Has anyone else had this trouble?
