i recently tuned my car after installing test pipe exhaust intake and my cel came on, my cel never came on for 2 months before tune then once i had it tuned the raw gas smell went away but my cel came on and the o2 sensor is constantly coming lose and rattling as it didnt before maybe from the cold weather, i know 06+ are sensitive but are there any solutions to splice in ? my wrx cel fix was a wire splice... any suggestions

 

drill a little hole on the sensor and on the bung. safetywire in a positive manner, that'll hold the bugger on there.
