Hey i got a code 43, so idid my research and i wen tout and bought a brand new OEM o2 sensor.. what else could be the problem.. im runing mad rich

 

hey i got the same thing, are you running a header and what brand o2 did you buy.

 

the problem is probably that you are running mad rich then.

 

yes runing a header

i bought a "walker" o2 sensor

 

 

valves?

 

fuel injector stuck open?

 

when did you last adjust your valves?

 

did you replace the o2 sensor yet?

 

i always stick with oem parts....i havent had a problem yet....its worth the extra money...

you sell the lude yet dark??

 

The 43 code is usually a bad O2 sensor. It can also be the FPR, fuel filter, or possibly injector or bad gas from what I've seen and read.

Walker is OK. I had an issue with 43 CEL and bought exactly the same sensor. Also replaced the fuel filter and adjusted valves. It helped.

 

ya walker should be good


i gotta change the plugs.. the fuel filter was just hcanged ...

maybe ill see if he can do a valve adjustment too

 

get an o2 sim to get rid of that light

 

where can you get an o2 sim....HONDA....autozone...pepboys?

 

Check for air leaks. #1 cause of mad rich engines. This overly rich condition is probably what fouled your O2 sensor. Was it really carboned up? When I read rich running threads, I always see people that ask if they changed their fuel filter. Please explain to me how a restriction in fuel delivery can make a engine run rich.

 

i replaced a fuel line (soft rubber line... cause it was leaking... and its not leaking anymore

maybe its kinked or smoetings wrongw ith it?

 

No, I was refering to vacuum leaks.

 

deng.....i have fu**kin 3 codes i found out 21, 23, and 43...on my h22a....i want everything to be back....HELP
