Well, I gave up trying to get the plug apart, couldn't budge it. So, instead, I cut the wires at the sensor. That allowed me to get my MC wrench on the sensor and get it off easy enough.
Then I used needle-nose pliers to hold each wire and trim the insulation, and connected to the new sensor wires with crimp connectors. I looped the excess up to a wire bundle on the firewall. I will not have this problem when I need to replace the sensors next time, now I have plenty of slack in the wires to cut and connect.
so i have a 2004 verona also about 110 k
and finally getting the P0171 P0174 and P0153 O2 sensor codes.
my mechanic friend is simply refusing to let me believe it's only a matter of the O2 sensor. He keep saying there are many reasons for the thing to read oil running lean. P0153 is Os sensor slow circuit or something like that, should i try to change the O2 sensor first or just take it to the shop
*there were problems with the cars electrical system, i had to replace the fuse harness
I'd suggest first conducting the preliminary maintenance as described in the article and then clearing the ECU codes (battery disconnect or with scan machine), followed by another scan to observe what codes return and pop up first. This will allow you to better diagnose the problem.
