Stupid O2 sensor wire. I repaired it 3 times now. Each time i soldered and used heat shrink.



Anyhow code 17 makes you get 275 kms on one tanks of gas vs 450+ kms



stupid stupid o2 sensor wire. I thikn i'm going to just run a brand new wire from the o2 sensor connector through the firewall and cut and splice into the ECU harness

 

at the hardware store they have these little electrical connectors...if you get two and attach one to each wire (the one coming from the O2 and the other leading down to it) ...you then have two plugs to just attach to each other. I replaced my O2 sensor a few weeks ago and just did this...worked out great...good luck
