1990 accord ex is what i ran a code search on. it said codes12 and 43. 12 is the egr so i replaced that. 43 is the fuel supply system? that seems kinda broad to me. so if anyone knows i would b thankful. the car tends to hesitate when giving it gas to a point then takes off like a bat outa hell. i thought fuel injector, but code says 43. and fuel injector code is 16.

 

Code 43 can be the oxygen sensor or fuel supply system.

 

it was the o2 sensor. b4 i ownd the car we replaced the fuel pump and fuel filtr. so the othr thing it could have been o2. so thanx gangstr
