Well.. took the EGR valve off today while replaceing my thermostat (seperate issue)
it was definitely sticking.. cleaned it up and put it back on.. so (for now) 3 of the codes are gone.. the O2 sensor.. the EGR flow restricted.. and the Aux Emissions one.. however I've still got:
p0172 - Too Rich, bank 1,
p0300 - Random Misfires..
Gonna try some seafoam I just got.. to see if that cleans up some.
