i'm having problems with my honda accord 93 ex coupe... i keep on changing the oxygen sensor before the cat converter..... when the check engine light goes on it shows code 43 all the time..... when it it lights up, the car runs sluggish or sometimes its like being choked..... i've changed the fuel filter, distributor cap and rotor, and the oxygen sensor but not the fuel pump yet.... do you think its the fuel pump? there was one incident that when i stepped on the gas it didn't have power. but when i stepped on it again hard the power came back.... and when the i turn off the engine the engine light goes off too..... then after driving it for a while it lights up again... please help me..... thanks....
