Codes are 17535 fuel trim bank 1 system too rich:
P1127-35-10 intermittent

Check your vacuum lines. Especially the one in front going from intake manifold to the DV. It has tendency to rub open where it crosses below the metal coolant line.
Second one that usually goes is the one on the rear that goes from intake manifold to the FPR.
