has anyone seen code 43 its a fun one. i cant get rid of it. changed every god damn thing possible and my car still gets code 43 randomly and bogs out like mad. my last 2 cars both had it and the only thing the same that i swapped over was the intake manifold and sensors but code 43 doesnt have anything to do with that i dont think.

when i research it it says main prob is o2 sensor but mine is disabled in the ecu.

it then says change. pump/filter/injectors. done all that to. changed fpr to.
im running 44 psi at my fpr. when i get the code it feels like im riding a bull the car bucks so hard.

usually takes about 45-60 mins of constant driving and then BAM CODE 43 UP MY ASS AND MY CAR BOGS. yet i can take 20 pizza deliverys in one day and not have one problem with it. its fucking confusing

 

sometimes simply turning the car off and on makes it go away but then comes back later sometimes
which makes diagnosing it really hard

 

Do u have a fuel pressure gauge or wideband to confirm you have steady 44psi when the bucking happens ?

 

definetly not steady fuel pressure when the bucking comes on. the FPR gauge goes fucking crazy up and down

 

 

+1 to Pops....

OP,Just because its disabled in the ecu, doesnt mean a loose wire or something along those lines wont cause the problem.

 

the fucked up thing is its intermitant. i can drive for weeks and weeks and never have the problem.

i mostly get it on longs trips to and from tampa/orlando

 

neil sutton did my wiring so im pretty sure thats not the issue. unless something came loose somehow

 

how can i test an o2 sensor thats disabled in the ecu i dont understand?

if its disabled a loose 02 wire dont matter the ecu dont even read it.

 

Orealllyyyy. I know you aren't running Hondata but check this out.Hondata • View topic - Throwing O2 sensor CEL after tuning on Hondata
Pm anytime. I'm assuming we got the major problems under control?
