[quote=JasonST;3140417]Code 43 means theres something wrong on the o2 circuit or fuel system, here are the possible problems.
o2 sensor
egr valve
fuel injectors
fuel injector resistor
fuel pump
fuel pressure regulatior

how do i check if these things are in working order? also if it were my o2 sensor or egr valve, wouldnt i throw a different code for these? if any of these were bad what kind of problems would i be having? thanks
