this code came up only once until i took the car to go snowboarding. it came up twice. one on the way there and again on the way back. i notice when it goes on (eng light goes and stays on) there's hesitation during acceleration. when its off, everything's good(obviously)

i looked it up and code 43 means 'fuel supply system'. does this mean the engine is not getting enough fuel? could my fuel filter be clogged ?

its very possible.. is it like a bogging feeling/sound? cuz if so, me and this guy made a thread a while back about both of our cars bogging out right after you start it..

he took it to acura and they said that his spark was jumping from the plug wires or something.. cant exactly remember what was said but do a search under my name as creator and you might find it

 

try resetting ecu, if still showes up check ur o2 sensor it might of went bad, its usually a bad o2 sensor tho, also u can replace ur fuel filter if its old

 

yea, i replaced the fuel filter just now so we'll see if that fixed it. if not, i'll replace the o2. thanks for the replies

 

I had the similar hesitation issues and code 43, it was my o2 sensor. Order a denso from http://www.sparkplugs.com .

 

the last time i posted on this topic i replaced the fuel filter, resetted the ECU, code went away. now its come back and acceleration is sluggish/hesitating. its also throwing code 1 but i already know how to fix that.

could it be that the fuel pump is going? injectors?

 

i resetted the ECU and after driving it for awhile, it started to hesitate then the engine light went on. can anyone help?

 

change the o2 sensor

 

so im having same issue. doesn't feel like its bogging at all.ive got a da9 with b20b4 97-3 head and pr4 ecu. i replaced the o2 sensor with one i had laying around that was in good condition. the code went away i even took it for a rip to see if it would come back and it didn't. at this point i hadn't had it insured. that was a week ago. today i insured it and went to go drive and 60 seconds into my trip it came back on throwing code 43 which is bizarre. would that have anything to do with my gas gauge not working? (wich im also working on trying to get working) like would it throw a code 43 if the gauge wasnt working? tomorrow im replacing the spark plugs/wires, o2 sensor and fuel filter. i guess ill start there and see if thats the issue but i am wondering about the gauge being related to my code 43
