Code 43 is Fuel System, perhaps you're running way too rich on boost?

 

its prolly your o2. code 43 sucks.

 

ok i will change the o2 again and see what happends thanks for all the help

 

im having the same code, after checking the plugs, (whiteish color) and now expierencing low end (under 2k) misfire, i believe the code discription is right, you know, fuel supply. but never rule out the 02 sensor, but thats probably not it.

 

oh yea, fuel injectors, could be an issue. just because there working dosent mean there working properly, like the spray pattern may be horrible, or they could be dirty and clogged up,

you say after 6 psi, the code throws,, well, your probably getting into a lean condition, just my guess.
but defidently check the plugs

 

thanks for the help everyone
