and once again ANOTHER problem has came up.

15 - Mixture ratio is too lean despite feedback control; fuel injector cloggedand34 - Detonation (Knock) Sensor

If i fix the injector problem will the knock sensor code go away or is is just bad?

if ya have a injector clogged man your gona run lean on one injector..or are they all like that?..you should just replace em all with some from a junk yard..get like 8 of em and play till ya have a good running set..if nothing changes..then its another issue and more information is needed.
