freaking llama. i thought i had this cured last night. now today i redid my timing belt, turned the car over, and bam it threw codes 10 and 43.

i was previously throwing just code 10.

im a little annoyed at this point! Before i put this motor in the car i had no CELs. Now I have two!

all of the sensors are the same as before I put this motor in the car so I know I messed up somewhere. Going to go over the wiring to make sure nothing is like backwards or soemthing.

Anyone with input lmk

 

When I had 43 it was my o2 sensor. Try however reseting the ECU and see what happens.
