P0057 HO2S Heater Control Circuit Low (Bank 2 Sensor 2)
P0037 HO2S Heater Control Circuit Low (Bank 1 Sensor 2)

That tells me the oxygen sensors are starting to fail, well at least the heater aspect to it. Besides checking the connections, if they are ok then that means the sensors need replaced. They are only post cat sensors so they will only give you a CEL.

P0505 is a malfunction with the idle air. Since we do not use an idle air valve, this code can usually be cured by cleaning the throttle body completely. This link goes into this code a bit further. Remember do NOT remove or loosen the sensors and throttle motor unless you have a voltmeter or scanner to put it back right. Just grab a can of carb cleaner and go to town, wiping the butterfly and TB.

p0037 and p0057

can these be fixed with 02 delete from token solutions? thanks again

With a FULL sim/delete such as what Tokensolutions offers. What you have are heater codes and i believe just a sim takes care of the P0420 P0430 issue.

In theory you could just add a resistor to fool the heater portion, though with no heater the delayed response of the o2 could create issues as well.
