codes p0135 & p0155 
Hey guys, just finished up a cam and lt's install on my car. Is this normal for these codes to be given right now? The car ran just fine before the install. Its not tuned yet. I deleted the AIR on the car. I just want to make sure there is nothing wrong before i take and have the car tuned and they wont tune due to the fact there is a malfunction somewhere. Oh, and the codes mean oxgen sensor heater circut malfunction. Both sides. Is this normal at this point? Should i be replacing them before the tune? Ok before

did you put the O2 sensors back in? if not thats why your throwing them... secondly... even after I put them back in on my long tube *I was using simulators* i still threw the code... I dont think it will hurt anything its just running open loop so your probally running rich... notice any kind of popping in the exhaust at high rpm?
