To change the problematic sensor requires a special socket which can be bought at that parts store along with an aftermarket O2 sensor. That's about as inexpensive as it's going to get.

Replying to: obyone (Feb 12, 2009 2:28 am) I scrounged for the money for a proper diagnostic and it turns out both upstream o2 sensors need to be replaced and the max airflow sensor as well. The damage is going to be 1000 dollars. Thanks for the reply
