I am throwing a code 16 and code 43....please help!!
My car runs for about 15 minutes then I get a code 16 and code 43 come up.
I recently had my main relay re-soldered, fuel injectors cleaned and new fuel filter installed. I thought that these checks and replacements would rid of these annoying codes.
-I am going to change my O2 Sensor.
-I have not checked the fuel pump....but it should be good. It is a Holly.
Does anyone else have any ideas??????

16- is fuel injectors
43- is fuel suplly system
try changing your fuel pump and filter it might fix it

if you didnt have these before.....you obviously screwd something up while messing with your fuel system...check the wiring, make sure the injector clips are in tight, make sure main relay soldering is still good etc...
it has nothing to do with the o2 sensor, leave it alone.
was the fuel pump working before you did all that stuff?

The O2 sensor IS whats responsible for generating the Fuel Supply Code. That does not mean that the O2 is bad however, but the 'reading' that the O2 is giving to the ECU is such that the ECU wants to trim the fuel injector pulse width becuase its running too lean/rich. When the ECU's Long Term Fuel Trim gets to +/- 20%, this code will get thrown.
What engine/ecu/modifications have you done? What the maintenance history looking like?

Do you think perhaps that when I took my injectors out and forgot to relieve the fuel pressure in the fuel pump and fuel filter that these codes could be set???
