Well finally swaped my 5.3 to a 6.0 yesterday and have gotten the codes po171 banks 1&2 and po174 bank 1&2 i checked for vaccum leaks by spraying the intake manifold with no jump in the idle checked a spark plug tip and its like a off white color. i installed delphi 42# injectors with the motor swap. What to do next?

 

Have you retuned it yet?

 

yep its running a wheatley tune

 

heres photos of the spark plug, i should also mention that the truck doesn't like to start until i crank it about 4 times.

 

Looks lean to me. Get it checked out.

 

im assuming you mean contact wheatley, do you think my starting issue could be from running too lean?

 

I am sending you out a retune

 

Thankyou Wheatley! I appreciate you being on top of this for me! Im sure you know but sent you a email with the freeze data from the scanner if that helps you... Thanks again!

 

Yes sir I did get that,check to make sure you have no vaccum leaks or anything also

 

yep, i will double check everything!
