What is the O2 sensor code for a obd1 GS-R? i put headers on with a 2.5 collector then 2 weeks later an engine code popped up. number 43 fuel supply system

 

here is every code that honda has

ECU codes:

0 ECU
1 Oxygen Content
3 Map Sensor
4 Crank Angle Sensor
5 Map Sensor
6 Coolent Temperature
7 Throttle Angle
8 TDC Position
9 No 1 Cylinder Position
10 Intake Air Temperature
63 Intake Air Temperature
12 Exhaust Gas Recirculation System
13 Atmosphere Pressure
14 Electronic Air Control
15 Ignition Output Signal
16 Fuel Injector
17 Vehicle Speed Sensor
20 Electronic Load Detector
21 VTEC Solenoid Valve (1.8L GSR)
22 VTEC Oil Pressure Switch (1.8L GSR)
23 Knock Sensor
30 TCM Signal A
31 TCM Signal B
41 O-2 Sensor Heater
43 Fuel Supply System
45 System Too Rich or Too Lean
48 Primary Heated O-2 Sensor
54 Crankshaft Speed Fluctuation Sensor
61 Primary O-2 Sensor Circuit
63 Secondary O-2 Sensor Circuit
67 Catalyst System
70 Automatic Transaxle
71-74 Random Misfire
80 Exhaust Gas Recirculation
86 Engine Coolant Temperature Circuit
90 Evaporative Emission Control System Leak Detected
91 Fuel Tank Pressure Circuit
92 Evaporative Emission Control System Insufficient

what code are you throwing?

 

i guess its not the o2 sensor then. its throwing a 43 fuel supply. do you know wat it might be.

 

my guess it would be your injectors..but it be a number of things..

 

a good example of the problem iam having is when i start the car in the morning an i drive off for work. the car would start to back fire real bad an wont let me go pass a 3k rpm or 3.5 or 4 depending. but wen i punch it...it goes through an stops breaking up. an the it will do it again for a little. i let the car warm up an it still does it. i change the spark plug wires an it still does it. i havent change the spark plugs yet thou

 

but after awhile the car will run fine an the check engine light will come on. the 43 code. and the it will come to a low idle... lower the 750 rpms at a stop in neutral.

 

hmm..im stumped..bump for this poor guy, and because i want to know!
