Code P1336? Help Well i went to have my car scanned for codes today. And found that i was throwing this code P1336. I did a search and found out that guys that have switched computers throw this code and have to have there computer re-learn the motor. Is this correct? If so, my car has already been tuned so does that mean if i have it reflashed will i lose the tune that is on the car now? Any help would be apperciated. Thanks

Another question my car was also throwing these codes: P0134, P0135, P0155 and i know that all those are O2 sensor codes my question is, do i need to worry about them? Do they effect the way the car runs? I know i dont have to worry about the rear ones but are these codes for the front or rear ones? Thanks

You can find detailed diagnostic steps for all of your DTC's here.
You won't lose your tune performing this re-learn procedure.
Regarding the O2 codes, anything affecting a 'Sensor 1' can dramatically affect the performance of your engine if desire to run in Closed Loop. In Closed Loop, the PCM uses feedback from the front O2 sensors (S1's) to alter fueling as required to aim for maintaining a stoichiometric (14.7:1) air-to-fuel ratio.
