O2 sensor replacment

[theironm0nk]

first off wow what an improvement there was a major hp jump in the lower rpm.

Replacing your O2 sensor is not that hard at all if you have wd-40 and a pair of mechanic gloves

If your car is over 100,000 miles then change it if you never did.

One word of warning if the O2 sensor is in the down pipe be careful the sensor can rip the thread out of the down pipe
