Terrible gas mileage in 96 civic
My gf's 96 civic cx is getting terrible mileage. shes getting just over 250kms a tank and it costs her roughly 40 to fill. I recently changed the plugs, cap, rotor, fuel filter and put on a cold air kit which helped a little bit maybe an extra 25kms a tank.
Im thinking the catalaytic converter is plugged or her fuel pressure regulator has gone south. Anyone have any ideas?
The converter on her car is a one piece design that bolts directly to the cylinder head so checking it would be pretty tough.
