I'm having a problem with my c5z. Its stumbling under acceleration and cruise. I thought it was a ccoilool problem. Anything below half throttle will big than it while stop and take off real fast. I think it is from the oxygen sensors as it only does it when it rains or its damp outside. I have headers on the car and I didn't have the extenders so I cut and splice the rear o2s the front plug. I will try and get the codes at lunch today. I was just wondering of bad sensors would cause something like this before I bought new ones
