P0135 - HO2S Heater Circuit Bank 1 Sensor 1
P0152 - HO2S Circuit High Voltage Bank 2 Sensor 1
P0302 - Cylinder 2 Misfire Detected
I would check the plugs, wires and check for any leaks in the intake tract.

That is def. a possibility. I had a missfire and a P0135 from plug wire fouling out. I guess when the cylinder missfired the unspent gases went down stream and caused the P0135. I only say that b/c I know the wire was bad and have not gotten either codes since. I would still checks things over and if it doesn't happen again I would not worry about it.
every once in a while i get a p0135 code in my car. what coudl this be? i figured it was from the headers and the plug was cold. i only see this on start up? now u have me worried its something else. i was getting a p0155 before, the pass side... is it just cause headers or faulty o2? or another problem? after i swithced o2s the p0155 went away and i get the p0135 sometimes. hmmm

im saying i only got the o2 codes and no misfire and it only comes on from a cold start, thats it. car runs fine besides that and at WOT both o2s are locked on the same number, 935
